Real-space observation of nanoscale magnetic phase separation in dysprosium by aberration-corrected Lorentz microscopy

Takuro Nagai, Koji Kimoto, Koji Inoke, and Masaki Takeguchi

Phys. Rev. B 96, 100405(R) (2017) - Published 19 September, 2017

Nanoscale magnetic phase separation in dysprosium has been revealed by aberration-corrected Lorentz microscopy. The in-plane magnetization distribution of the coexisting magnetic phases has been visualized successfully by combining high-resolution Lorentz microscopy with the transport-of-intensity equation method. The phase separation of the ferromagnetic and the helical antiferromagnetic (HAFM) phases results in the formation of static magnetic solitons at around 130 K in the absence of external magnetic field. External fields of up to about 11 kOe induce nanoscale phase separation of the HAFM, the distorted HAFM, and the fan phases at 142 K. The developed technique for the high-resolution observation of fine magnetic structures is a valuable addition to the modern toolbox of magnetic materials research.

Direct observation of magnon-phonon coupling in yttrium iron garnet

Haoran Man, Zhong Shi, Guangyong Xu, Yadong Xu, Xi Chen, Sean Sullivan, Jianshi Zhou, Ke Xia, Jing Shi, and Pengcheng Dai

Phys. Rev. B 96, 100406(R) (2017) - Published 27 September, 2017

The ferrimagnetic insulator yttrium iron garnet (YIG) has been widely used in microwave and spintronic devices. Anomalous features in spin Seeback effect voltages have been observed in Pt/YIG and attributed to magnon-phonon coupling. Using inelastic neutron scattering to map out low-energy spin waves and acoustic phonons in YIG as a function of increasing magnetic field, the authors find that the magnon-phonon interaction enhances the hybridized scattering intensity at the magnon-phonon dispersion crossing points in zero field. These results go against the expectations of conventional spin-lattice coupling, calling for a different explanation of the magnon-phonon interactions and the resulting magnon polarons in YIG.

Quasiparticle excitations and evidence for superconducting double transitions in monocrystalline U0.97Th0.03Be13

Yusei Shimizu, Shunichiro Kittaka, Shota Nakamura, Toshiro Sakakibara, Dai Aoki, Yoshiya Homma, Ai Nakamura, and Kazushige Machida

Phys. Rev. B 96, 100505(R) (2017) - Published 18 September, 2017

To address the long-standing question of double phase transitions in the superconducting state of U1-xThxBe13, the authors study the quasiparticle excitations and magnetic response using a monocrystalline sample. The high-resolution heat-capacity and magnetization data demonstrate that the lower-temperature transition is between two superconducting states with different gap symmetries. Quite surprisingly, the C(T,H,ph) data strongly suggest that the superconducting gap is fully open over the Fermi surface in U0.97Th0.03Be13. The present thermodynamic results entirely overturn a widely believed idea that nodal quasiparticle excitations occur in uranium heavy-fermion superconductivity with broken time-reversal-symmetry.

Lead palladium titanate: A room-temperature multiferroic

Elzbieta Gradauskaite, Jonathan Gardner, Rebecca M. Smith, Finlay D. Morrison, Stephen L. Lee, Ram S. Katiyar, and James F. Scott

Phys. Rev. B 96, 104104 (2017) - Published 7 September, 2017

The authors demonstrate room-temperature multiferroic (ferroelectric-ferromagnetic) behavior in lead titanate, in which about 30% of the titanium is substituted by palladium. Palladium is an unusual element with an instability to ferromagnetism under some special conditions. Typically, it has not been easy to incorporate it into perovskite oxides – the most common structure for ferroelectric device materials. Although palladium is expensive, commercial devices like ferroelectric memories often use very thin films, for which the added cost of palladium is negligible. Thus, the present study combines basic new physics of the first multiferroic palladium compounds with potential commercial devices.

Origins of Willis coupling and acoustic bianisotropy in acoustic metamaterials through source-driven homogenization

Caleb F. Sieck, Andrea Alù, and Michael R. Haberman

Phys. Rev. B 96, 104303 (2017) - Published 11 September, 2017

In addition to conventional acoustic properties (mass density and compressibility), recent research has shown that inhomogeneous acoustic media may require coupling tensors between effective volume strain and momentum fields. These coupling tensors imply conversion between monopolar and dipolar motion in the effective material response. Intrinsic coupling between strain and momentum is known as Willis coupling in elastodynamics, and it is analogous to bianisotropy in electromagnetism. This paper investigates the microscale and mesoscale effects that lead to Willis coupling, studies the proper homogenization of acoustic metamaterials with non-negligible Willis coupling, and demonstrates the impact of Willis coupling on defining physically meaningful effective material parameters.

Magnetic order, hysteresis, and phase coexistence in magnetoelectric LiCoPO4

Phys. Rev. B 96, 104420 (2017) - Published 15 September, 2017

Magnetoelectric materials are characterized by a coupling of electric and magnetic degrees of freedom, which can be brought about when magnetic ordering breaks inversion symmetry. This is the case in LiCoPO4, which displays one of the largest magnetoelectric effects among transition metal compounds. Using neutron diffraction in combination with state-of-the-art high-field magnet technology, the authors of this paper study the magnetic structures and phase diagram of LiCoPO4 in fields up to 25.9 T. It is shown that the known magnetoelectric response is tied to commensurate magnetic order, while an incommensurate cycloid phase allows electric polarization along a direction yet to be probed experimentally.

Nonlocal magnon-polaron transport in yttrium iron garnet

Phys. Rev. B 96, 104441 (2017) - Published 29 September, 2017

Magnon-polarons are coherently mixed quasiparticles – half magnon, half phonon – and are generated by magnetoelasticity. Though predicted by Kittel long ago, their effect on spin transport was discovered only recently in yttrium iron garnet (YIG) using optical and local spin Seebeck effect (SSE) experiments. In the latter, magnon-polarons are manifest as resonant peaks in the SSE signal as a function of magnetic field. Here, the authors show that they also show up in the nonlocal SSE, with a surprising twist: measured nonlocally, the magnon-polaron peak turns into a dip. The authors show that this crossover is a consequence of the magnon physics underlying the SSE: thermal generation and diffusive backflow of magnons in YIG compete, which can generate any sign for the magnon-polaron anomaly in nonlocal experiments.

TRILEX and GW+EDMFT approach to d-wave superconductivity in the Hubbard model

J. Vučičević, T. Ayral, and O. Parcollet

Phys. Rev. B 96, 104504 (2017) - Published 5 September, 2017

In high-temperature superconductors, the superconductivity appears on the verge of Mott localization and is mediated by collective electronic excitations. Here, the authors present a general theoretical framework (TRILEX) that combines the ideas of DMFT and spin-fluctuation theory, and is shown to capture both the d-wave superconductivity and the Mott insulating phase in the Hubbard model. The emphasis is laid on the local scattering between the electrons and the effective long-range bosonic degrees of freedom. The renormalized electron-boson vertex is obtained from a quantum Monte Carlo solution of a self-consistent single-impurity effective model. Therefore, the calculation is of significantly lighter weight compared to the minimal cluster DMFT required for the same purpose. Additionally, both the level and flavor of the approximation are variable, in a fully controlled manner.

In addition to conventional acoustic properties (mass density and compressibility), recent research has shown that inhomogeneous acoustic media may require coupling tensors between effective volume strain and momentum fields. These coupling tensors imply conversion between monopolar and dipolar motion in the effective material response. Intrinsic coupling between strain and momentum is known as Willis coupling in elastodynamics, and it is analogous to bianisotropy in electromagnetism. This paper investigates the microscale and mesoscale effects that lead to Willis coupling, studies the proper homogenization of acoustic metamaterials with non-negligible Willis coupling, and demonstrates the impact of Willis coupling on defining physically meaningful effective material parameters.

Magnetoelectric materials are characterized by a coupling of electric and magnetic degrees of freedom, which can be brought about when magnetic ordering breaks inversion symmetry. This is the case in LiCoPO4, which displays one of the largest magnetoelectric effects among transition metal compounds. Using neutron diffraction in combination with state-of-the-art high-field magnet technology, the authors of this paper study the magnetic structures and phase diagram of LiCoPO4 in fields up to 25.9 T. It is shown that the known magnetoelectric response is tied to commensurate magnetic order, while an incommensurate cycloid phase allows electric polarization along a direction yet to be probed experimentally.

Magnon-polarons are coherently mixed quasiparticles – half magnon, half phonon – and are generated by magnetoelasticity. Though predicted by Kittel long ago, their effect on spin transport was discovered only recently in yttrium iron garnet (YIG) using optical and local spin Seebeck effect (SSE) experiments. In the latter, magnon-polarons are manifest as resonant peaks in the SSE signal as a function of magnetic field. Here, the authors show that they also show up in the nonlocal SSE, with a surprising twist: measured nonlocally, the magnon-polaron peak turns into a dip. The authors show that this crossover is a consequence of the magnon physics underlying the SSE: thermal generation and diffusive backflow of magnons in YIG compete, which can generate any sign for the magnon-polaron anomaly in nonlocal experiments.

TRILEX and GW+EDMFT approach to d-wave superconductivity in the Hubbard model

J. Vučičević, T. Ayral, and O. Parcollet

Phys. Rev. B 96, 104504 (2017) - Published 5 September, 2017

In high-temperature superconductors, the superconductivity appears on the verge of Mott localization and is mediated by collective electronic excitations. Here, the authors present a general theoretical framework (TRILEX) that combines the ideas of DMFT and spin-fluctuation theory, and is shown to capture both the d-wave superconductivity and the Mott insulating phase in the Hubbard model. The emphasis is laid on the local scattering between the electrons and the effective long-range bosonic degrees of freedom. The renormalized electron-boson vertex is obtained from a quantum Monte Carlo solution of a self-consistent single-impurity effective model. Therefore, the calculation is of significantly lighter weight compared to the minimal cluster DMFT required for the same purpose. Additionally, both the level and flavor of the approximation are variable, in a fully controlled manner.
