Anharmonicity of the antiferrodistortive soft mode in barium zirconate BaZrO3

Petter Rosander, Erik Fransson, Cosme Milesi-Brault, Constance Toulouse, Frédéric Bourdarot, Andrea Piovano, Alexei Bossak, Mael Guennou, and Göran Wahnström

Phys. Rev. B 108, 014309 (2023) - Published 25 July, 2023

BaZrO3 is one of the very few perovskites that is claimed to remain cubic down to 0 K, but its tendency towards an antiferrodistortive (AFD) instability has fueled a lot of debates. Here, the AFD phonon mode is studied using inelastic neutron scattering (INS) and inelastic x-ray scattering (IXS), combined with a computational approach including anharmonicity. Both classical molecular dynamics (MD) and a self-consistent phonon approach are used, the latter including quantum fluctuations of the atomic motion. This robust description of the AFD mode clarifies that BaZrO3 stays cubic down to 0 K.

Magnetic anisotropy, magnetoelastic coupling, and the magnetic phase diagram of Ni0.25Mn0.75TiO3

A. Elghandour, L. Gries, L. Singer, M. Hoffmann, S. Spachmann, M. Uhlarz, K. Dey, and R. Klingeler

Phys. Rev. B 108, 014406 (2023) - Published 5 July, 2023

Magnetic anisotropy describes the tendency of a material to exhibit different magnetic behavior along different crystallographic directions. Here, the authors mix two antiferromagnets, namely MnTiO3 and NiTiO3, to form Ni0.25Mn0.75TiO3. The parent magnets are of competing anisotropy. The former has an easy magnetic axis along the c axis, whereas the latter has an easy magnetic plane within the ab plane. The authors also shed light on the doping effect upon the long-range magnetic order, emergent magnetic phases, and the magnetic entropy consumption in comparison to the parent magnets. Finally, they employ different thermodynamic probes to build a complex and rich anisotropic magnetic phase diagram of Ni0.25Mn0.75TiO3.

Experimental verification of the reflection matrix description in linear magneto-optics

Carmen Martín Valderrama, Mikel Quintana, and Andreas Berger

Phys. Rev. B 108, 014415 (2023) - Published 12 July, 2023

The magneto-optical Kerr effect (MOKE) is described by a dielectric tensor ϵ that contains magnetization dependent terms, whose impact on reflected light is solved as an electromagnetic boundary problem. Corresponding solutions for the Jones-type reflection matrix R have been known for decades, but have not been rigorously confirmed in experiments. Here, the authors have verified that the MOKE coefficients of R describe an ellipsoid (ellipse) for a random three-dimensional (two-dimensional) magnetization vector as predicted. The experiments accomplish the simultaneous measurements of all R components through generalized magneto-optical ellipsometry.

Drag resistance mediated by quantum spin liquids

Raffaele Mazzilli, Alex Levchenko, and Elio J. König

Phys. Rev. B 108, 014425 (2023) - Published 24 July, 2023

Probing quantum spin liquid behavior in atomically thin materials is a challenging task. The authors propose here an experimental setup consisting of two metallic layers separated by a thin quantum spin liquid. The voltage induced in one of the metals by injecting a current in the other metal probes the nontrivial dynamics of gapless excitations in the quantum spin liquid. This analysis captures U(1) and ℤ2 quantum spin liquids and may find realizations in materials such as α-RuCl3, 1T-TaSe2, and 1T-TaS2.

Exciton superfluidity in two-dimensional heterostructures from first principles: Importance of material-specific screening

Rune Højlund, Emil Grovn, Sahar Pakdel, Kristian S. Thygesen, and Fredrik Nilsson

Phys. Rev. B 108, 014506 (2023) - Published 20 July, 2023

van der Waal heterostructures can host long-lived excitons that can condense and exhibit superfluidity at low temperatures. In this paper, Højlund, Grovn and coworkers derive a first-principles framework, based on existing open-source codes, that can be used to model these systems. This framework is then used to evaluate the exciton binding energies and superfluid properties of hundreds of different heterostructures. Based on these calculations, the authors propose optimized materials with superior properties compared to the standard platforms.

Dynamics of orbital degrees of freedom probed via isotope Sb121,123 nuclear quadrupole moments in Sb-substituted iron pnictide superconductors

T. Kouchi, K. Yoshinaga, T. Asano, S. Nishioka, M. Yashima, H. Mukuda, A. Iyo, T. Kawashima, and S. Miyasaka

Phys. Rev. B 108, 014507 (2023) - Published 20 July, 2023

Since the discovery of the iron-based high-temperature superconductors, the superconductivity mechanism related to spin fluctuations and nematic (orbital) fluctuations has been much discussed, but it is remains unclear. Here, the authors reveal that the isotope 121,123Sb nuclei with large quadrupole moments are a sensitive local probe to observe the dynamics of orbital degrees of freedom. This provides us with a new approach to investigate systematically the correlation between the superconductivity and both the nematic and spin fluctuations, even in polycrystalline samples.

Structure, stability, and superconductivity of N-doped lutetium hydrides at kbar pressures

Katerina P. Hilleke, Xiaoyu Wang, Dongbao Luo, Nisha Geng, Busheng Wang, Francesco Belli, and Eva Zurek

Phys. Rev. B 108, 014511 (2023) - Published 31 July, 2023

The recent results describing a room-temperature superconductor in the lutetium nitrogen hydrogen system have prompted an avalanche of work. In this computational study, a range of techniques from crystal structure prediction to prototype modification, produce an array of low-pressure dynamically stable Lu-N-H phases. None were thermodynamically stable. The best fit to the experimental EOS came from fluorite-type LuH2, while the highest estimated Tc (a meager 17 K) arose from an extremely thermodynamically unstable phase based on 50% N substitution (LuNH)

The recent results describing a room-temperature superconductor in the lutetium nitrogen hydrogen system have prompted an avalanche of work. In this computational study, a range of techniques from crystal structure prediction to prototype modification, produce an array of low-pressure dynamically stable Lu-N-H phases. None were thermodynamically stable. The best fit to the experimental EOS came from fluorite-type LuH2, while the highest estimated Tc (a meager 17 K) arose from an extremely thermodynamically unstable phase based on 50% N substitution (LuNH)
