Nonreciprocal Transport in Noncoplanar Magnetic Systems without Spin-Orbit Coupling, Net Scalar Chirality, or Magnetization
Satoru Hayami, Megumi Yatsushiro
We propose a new mechanism of nonlinear nonreciprocal transport in magnetic systems. By considering a noncoplanar magnetic ordering on a bilayer triangular lattice, we clarify that…
Nonlinear nonreciprocal transport in antiferromagnets free from spin-orbit coupling
Satoru Hayami, Megumi Yatsushiro
We theoretically propose a realization of a nonlinear nonreciprocal transport in antiferromagnets without relying on the relativistic spin-orbit coupling. Through the symmetry and…
Mean-field Study of Antiferromagnetic and Antiferroquadrupolar Orderings in Tetragonal CeCoSi
Megumi Yatsushiro, Satoru Hayami
We investigate the stability of the multipolar orderings in -electron material CeCoSi based on a self-consistent mean-field calculation for the effective localized model. This m…
Spin Conductivity Based on Magnetic Toroidal Quadrupole Hidden in Antiferromagnets
Satoru Hayami, Megumi Yatsushiro
We report our theoretical results on spin conductivity in antiferromagnets by focusing on the role of the magnetic toroidal quadrupole (MTQ) in electron systems. The MTQ is charact…
Nonlinear spin Hall effect in -symmetric collinear magnets
Satoru Hayami, Megumi Yatsushiro, Hiroaki Kusunose
We theoretically investigate a nonlinear spin Hall effect in -symmetric antiferromagnetic metals, which serve as an efficient spin current generator. We elucidate tha…
Analysis of model parameter dependences on the second-order nonlinear conductivity in -symmetric collinear antiferromagnetic metals with magnetic toroidal moment on zigzag chains
Megumi Yatsushiro, Rikuto Oiwa, Hiroaki Kusunose +1
A magnetic toroidal moment is a fundamental electronic degree of freedom in the absence of both spatial inversion and time-reversal symmetries and gives rise to novel multiferroic…
Multipole classification in 122 magnetic point groups for unified understanding of multiferroic responses and transport phenomena
Megumi Yatsushiro, Hiroaki Kusunose, Satoru Hayami
Mutual interplay between the electronic degrees of freedom in solids, such as charge, spin, orbital, sublattice, and bond degrees of freedom, is a source of cross-correlated phenom…
NQR and NMR spectra in odd-parity multipole material CeCoSi
Megumi Yatsushiro, Satoru Hayami
We theoretically study NQR and NMR spectra in the presence of odd-parity multipoles originating from staggered antiferromagnetic and antiferroquadrupole orderings. For the -elec…
Odd-Parity Multipoles by Staggered Magnetic Dipole and Electric Quadrupole Orderings in CeCoSi
Megumi Yatsushiro, Satoru Hayami
We investigate a possibility of odd-parity multipole orderings in a locally noncentrosymmetric tetragonal compound CeCoSi. By performing symmetrical and microscopic mean-field anal…
Atomic-Scale Magnetic Toroidal Dipole under Odd-Parity Hybridization
Megumi Yatsushiro, Satoru Hayami
Magnetic toroidal dipole (MTD) is one of a fundamental constituent to induce magneto-electric effects in the absence of both spatial inversion and time-reversal symmetries. We repo…
Classification of atomic-scale multipoles under crystallographic point groups and application to linear response tensors
Satoru Hayami, Megumi Yatsushiro, Yuki Yanagi +1
Four types of atomic-scale multipoles, electric, magnetic, magnetic toroidal, and electric toroidal multipoles, give a complete set to describe arbitrary degrees of freedom for cou…
