Observation of Magnetopiezoelectric Effect in Antiferromagnetic Metal EuMnBi2
Y. Shiomi, H. Watanabe, H. Masuda +3
We have experimentally studied a magnetopiezoelectric effect predicted recently for magnetic metals with low crystal symmetries. In EuMnBi2 with antiferromagnetic Mn moments at 77…
Nonreciprocal spin Seebeck effect in antiferromagnets
Rina Takashima, Yuki Shiomi, Yukitoshi Motome
We theoretically propose a nonreciprocal spin Seebeck effect, i.e., nonreciprocal spin transport generated by a temperature gradient, in antiferromagnetic insulators with broken in…
Spin-current coherence peak in superconductor/magnet junctions
Maki Umeda, Yuki Shiomi, Takashi Kikkawa +4
Coherence peak effects in a superconductor induced by a thermal spin current are reported. We measured inverse spin Hall effects induced by spin injection from a ferrimagnetic insu…
