Role of magnetic chirality in polarization flip upon commensurate-incommensurate magnetic phase transition in YMn${}_2$O${}_5$

S. Wakimoto, H. Kimura, Y. Sakamoto +4

We have performed simultaneous measurements of magnetic chirality by using polarized neutrons and electric polarization along the b-axis of single crystals of YMn${}^{4+}$(Mn${}_{1-x}$…
