Magnetoelectric control of spin helicity and nonreciprocal charge transport in a multiferroic metal

Daiki Yamaguchi, Aki Kitaori, Naoto Nagaosa +1

A multiferroic state with both electric polarization ($P$) and magnetization ($M$) shows the inherently strong $P$-$M$ coupling, when $P$ is induced by cycloidal (Néel-wall like) s…
