RKKY interaction as a probe of valley-dependent spin splitting and odd-parity nature in Floquet collinear magnets
Hou-Jian Duan, Yong-Jia Wu, Xiaoliang Xiao +3
Odd-parity magnets were recently proposed to emerge in collinear antiferromagnets (AFMs) via Floquet engineering, with valley-dependent spin splitting underlying the odd-parity spi…
