是一种具有多铁性的三方手性极性helimagnet。在这里，我们进行光学吸收测量onmagnetic fields。这种磁致变色现象是由于具有电子组态的离子的原子内激发从基态到激发态的跃迁几率与自旋有关。利用光频磁介电耦合，我们提出沿着轴6 T的亚铁磁和非公度磁相的分界线应在50 K附近。
is a trigonal chiral polar helimagnet with multiferroic nature. Here, we perform optical absorption measurements onin magnetic fields. The observed magnetochromism is attributed to the spin-dependent transition probability of the intra-atomicexcitation from theground state to theexcited state ofions with theelectronic configuration. Exploiting the magnetodielectric coupling in optical frequencies, we propose that the boundary between ferrimagnetic and incommensurate magnetic phases ofin 6 T along theaxis should lie at around 50 K.
