VO2 under hydrostatic pressure: Isostructural phase transition close to a critical endpoint

P. Bouvier, L. Bussmann, D. Machon, I. Breslavetz, G. Garbarino, P. Strobel, and V. Dmitriev

Phys. Rev. B 108, 144106 (2023) - Published 16 October, 2023

The authors unveil here new findings in the realm of phase transitions in VO2 single crystals, all achieved under hydrostatic pressure conditions. They provide experimental results, exploiting the observation of soft phonons through Raman spectroscopy and high-quality structural refinements. These findings offer a fresh perspective on phase diagrams, including a precise description of the M1-M1 isostructural transition occurring at a staggering 14 GPa. The study also reveals that isothermal compression at 298 K drives a thrilling journey close to the critical point. The authors present the first Raman signature of the elusive metallic X-phase, observed at pressures exceeding 32 GPa.

Nonlocal magnon transconductance in extended magnetic insulating films. I. Spin diode effect

Phys. Rev. B 108, 144410 (2023) - Published 12 October, 2023

Combining the nonlinear properties of ferromagnets with the spin-transfer effect promises to realize a “perfect” diode with pure spin conductors. Practical implementations are nonlocal devices that emit and collect magnons between two parallel electrodes on a magnetic insulator. A diode-like current-voltage characteristic appears, which is attributed to nonlinear enhancement of the low-energy magnon population. However, its amplitude is rather small and can be explained by the strong enhancement of magnon-magnon scattering near the diode threshold. This suggests conductance by a magnon fluid instead of a frictionless condensate.

Nonlocal magnon transconductance in extended magnetic insulating films. II. Two-fluid behavior

R. Kohno, K. An, E. Clot, V. V. Naletov, N. Thiery, L. Vila, R. Schlitz, N. Beaulieu, J. Ben Youssef, A. Anane, V. Cros, H. Merbouche, T. Hauet, V. E. Demidov, S. O. Demokritov, G. de Loubens, and O. Klein

Phys. Rev. B 108, 144411 (2023) - Published 12 October, 2023

Practical implementations of diode-like devices with pure spin conductors use magnon transport between two metallic electrodes deposited on a magnetic insulator. However, a diode-like response is only visible for a sufficiently large separation between the two electrodes. The authors attribute this behavior to the contribution of thermal magnons, which respond linearly to excitation and dominate the response for small separations. Their contribution decays rapidly with distance, revealing at large separations the nonlinear behavior that is associated with long-range propagating low-energy magnons.

Dynamic paramagnon-polarons in altermagnets

Charles R. W. Steward, Rafael M. Fernandes, and Jörg Schmalian

Phys. Rev. B 108, 144418 (2023) - Published 17 October, 2023

Altermagnetic states are qualitatively different from ferromagnetic and antiferromagnetic ones, as they are invariant under a combination of rotation and time reversal. The unique properties afforded by such symmetries have attracted significant attention by the community. Here, the authors unearth an unusual dynamic coupling that exists between the altermagnetic and lattice degrees of freedom, which resembles the Hall viscosity. This effect results in a hybridization between altermagnetic and phonon modes, enabling one to directly probe altermagnetic excitations in the phonon spectrum.

Electrical detectability of magnon-mediated spin current shot noise

Luise Siegl, Michaela Lammel, Akashdeep Kamra, Hans Huebl, Wolfgang Belzig, and Sebastian T. B. Goennenwein

Phys. Rev. B 108, 144420 (2023) - Published 18 October, 2023

The spin of so-called squeezed magnons has been shown to deviate from the common value ħ, with corresponding changes in the spin-current shot noise. The authors calculate here the magnitude of the concomitant voltage noise in the charge channel for a typical electrically detected spin pumping signal and find that it is significantly smaller than the inevitable Johnson-Nyquist noise. Their analysis thus provides important guidance for the challenges in experimentally detecting squeezed magnons through electrical noise measurements.

Skyrmion motion in magnetic anisotropy gradients: Acceleration caused by deformation

Ismael Ribeiro de Assis, Ingrid Mertig, and Börge Göbel

Phys. Rev. B 108, 144438 (2023) - Published 30 October, 2023

Skyrmions in weak parameter gradients behave similarly to current-driven skyrmions, moving uniformly along a fixed skyrmion Hall angle relative to the current direction. This study reveals a distinct type of motion that becomes relevant for large parameter gradients: skyrmions undergo significant profile changes, resulting in a nonuniform motion. They accelerate and follow curved trajectories. Leveraging this insight, the authors introduce novel strategies for suppressing the skyrmion Hall effect, both parallel and perpendicular to the gradient direction.

High-pressure behavior of the magnetic van der Waals molecular framework Ni(NCS)2

Phys. Rev. B 108, 144439 (2023) - Published 31 October, 2023

The ease of applying external stimuli, such as pressure, is an attractive feature for devices based on van der Waals materials. The authors report here the effect of pressure up to 8 kbar on Ni(NCS)2, a two-dimensional van der Waals magnet, using bulk magnetic susceptibility and neutron and x-ray diffraction. Ni(NCS)2 is found to be more compressible than metal halide analogues, with anisotropic compressibility both within the layers and between them. In addition to the large mechanical response, the magnetic ordering temperature is significantly enhanced: ΔTN /TN = 19%.

Constraints on a split superconducting transition under uniaxial strain in Sr2RuO4 from scanning SQUID microscopy

Eli Mueller, Yusuke Iguchi, Christopher Watson, Clifford W. Hicks, Yoshiteru Maeno, and Kathryn A. Moler

Phys. Rev. B 108, 144501 (2023) - Published 4 October, 2023

Strontium ruthenate continues to draw considerable scientific interest as an unconventional superconductor. One open question is whether the superconducting order parameter has a single component or two degenerate components. Here, the authors use scanning SQUID microscopy to test for a second superconducting transition in the superfluid density under application of symmetry breaking strain, a key prediction for a system with a two-component order parameter. The reported non-observation of a second superconducting transition constrains future models of unconventional superconductivity in this fascinating material.

Fractal nature of high-order time crystal phases

Guido Giachetti, Andrea Solfanelli, Lorenzo Correale, and Nicolò Defenu

Phys. Rev. B 108, L140102 (2023) - Published 9 October, 2023

In Floquet time crystals, characterized by the spontaneous breaking of time-translational invariance, observables exhibit oscillations with a period multiple p>2 of the driving. Here, a new, experimentally accessible, order parameter is introduced, able to detect time-crystalline phases regardless of the value of p. This unveils a rich landscape with self-similar fractal boundaries in the phase diagram of the long-range kicked Ising model. These features are explained within the theoretical framework, along with the emergence of the Zp symmetry in Bloch eigenstates.

Coexistence of extended and localized states in finite-sized mosaic Wannier-Stark lattices

Jun Gao, Ivan M. Khaymovich, Adrian Iovan, Xiao-Wei Wang, Govind Krishna, Ze-Sheng Xu, Emrah Tortumlu, Alexander V. Balatsky, Val Zwiller, and Ali W. Elshaari

Phys. Rev. B 108, L140202 (2023) - Published 10 October, 2023

The transport of quantum particles and their possible localization are fundamental concepts in physics. Such particles are known to get stuck in strong electric fields due to the Wannier-Stark effect. But what will happen with this particle localization if the electric potential is present only on every second site? To answer this question, the authors mimic here the behavior of quantum particles with light in optical waveguides (shown in the image) and demonstrate that in finite systems there are both extended states, carrying the transport, and localized ones that are stuck. This first step opens the possibility to use this system as an encoder of quantum information in a compact way.

Magnon-polaron driven thermal Hall effect in a Heisenberg-Kitaev antiferromagnet

Phys. Rev. B 108, L140402 (2023) - Published 4 October, 2023

The thermal Hall effect, where a transverse heat current is generated in response to a longitudinal temperature gradient, probes charge-neutral excitations in insulating quantum matter. By studying thermal transport in the Heisenberg-Kitaev antiferromagnet and spin liquid candidate Na2Co2TeO6, the authors find here that magnon polarons, i.e., hybridized phonons and magnons produced by spin-lattice coupling, govern the sign and magnitude of the observed signal. This is in contrast to a pure magnon transport theory, which fails to capture important features of the experiment.

Possible s±-wave superconductivity in La3Ni2O7

Qing-Geng Yang, Da Wang, and Qiang-Hua Wang

Phys. Rev. B 108, L140505 (2023) - Published 17 October, 2023

For the new high-temperature superconductor La3Ni2O7 under high pressure, the authors analyze its pairing mechanism and pairing symmetry in a bilayer two-orbital Hubbard model. By combining functional renormalization group in weak-to-moderate interaction regime and Gutzwiller approximation for its low-energy effective model projected to atomic one- and two-electron states in the strong-coupling regime, they find robust extended s-wave or s±-wave pairing as triggered by spin fluctuations.

Combining the nonlinear properties of ferromagnets with the spin-transfer effect promises to realize a “perfect” diode with pure spin conductors. Practical implementations are nonlocal devices that emit and collect magnons between two parallel electrodes on a magnetic insulator. A diode-like current-voltage characteristic appears, which is attributed to nonlinear enhancement of the low-energy magnon population. However, its amplitude is rather small and can be explained by the strong enhancement of magnon-magnon scattering near the diode threshold. This suggests conductance by a magnon fluid instead of a frictionless condensate.

Practical implementations of diode-like devices with pure spin conductors use magnon transport between two metallic electrodes deposited on a magnetic insulator. However, a diode-like response is only visible for a sufficiently large separation between the two electrodes. The authors attribute this behavior to the contribution of thermal magnons, which respond linearly to excitation and dominate the response for small separations. Their contribution decays rapidly with distance, revealing at large separations the nonlinear behavior that is associated with long-range propagating low-energy magnons.

Altermagnetic states are qualitatively different from ferromagnetic and antiferromagnetic ones, as they are invariant under a combination of rotation and time reversal. The unique properties afforded by such symmetries have attracted significant attention by the community. Here, the authors unearth an unusual dynamic coupling that exists between the altermagnetic and lattice degrees of freedom, which resembles the Hall viscosity. This effect results in a hybridization between altermagnetic and phonon modes, enabling one to directly probe altermagnetic excitations in the phonon spectrum.

The spin of so-called squeezed magnons has been shown to deviate from the common value ħ, with corresponding changes in the spin-current shot noise. The authors calculate here the magnitude of the concomitant voltage noise in the charge channel for a typical electrically detected spin pumping signal and find that it is significantly smaller than the inevitable Johnson-Nyquist noise. Their analysis thus provides important guidance for the challenges in experimentally detecting squeezed magnons through electrical noise measurements.

Skyrmions in weak parameter gradients behave similarly to current-driven skyrmions, moving uniformly along a fixed skyrmion Hall angle relative to the current direction. This study reveals a distinct type of motion that becomes relevant for large parameter gradients: skyrmions undergo significant profile changes, resulting in a nonuniform motion. They accelerate and follow curved trajectories. Leveraging this insight, the authors introduce novel strategies for suppressing the skyrmion Hall effect, both parallel and perpendicular to the gradient direction.

The ease of applying external stimuli, such as pressure, is an attractive feature for devices based on van der Waals materials. The authors report here the effect of pressure up to 8 kbar on Ni(NCS)2, a two-dimensional van der Waals magnet, using bulk magnetic susceptibility and neutron and x-ray diffraction. Ni(NCS)2 is found to be more compressible than metal halide analogues, with anisotropic compressibility both within the layers and between them. In addition to the large mechanical response, the magnetic ordering temperature is significantly enhanced: ΔTN /TN = 19%.

Superfluidity and superconductivity

Constraints on a split superconducting transition under uniaxial strain in Sr2RuO4 from scanning SQUID microscopy

Strontium ruthenate continues to draw considerable scientific interest as an unconventional superconductor. One open question is whether the superconducting order parameter has a single component or two degenerate components. Here, the authors use scanning SQUID microscopy to test for a second superconducting transition in the superfluid density under application of symmetry breaking strain, a key prediction for a system with a two-component order parameter. The reported non-observation of a second superconducting transition constrains future models of unconventional superconductivity in this fascinating material.
