Spin-charge coupling and decoupling in perovskite-type iron oxides (Sr${}_{1-x}$Ba${}_x$)${}_{2/3}$La${}_{1/3}$FeO${}_3$

Masaho Onose, Hidefumi Takahashi, Takashi Saito +10

The perovskite-type iron oxide Sr${}_{2/3}$La${}_{1/3}$FeO${}_3$ is known to show characteristic spin-charge ordering (SCO), where sixfold collinear spin ordering and threefold charge or…
