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…
