Antiferromagnetic Order in the Rare Earth Halide Perovskites CsEuBr${}_3$ and CsEuCl${}_3$

Daniel B. Straus, Tomasz Klimczuk, Xianghan Xu +1

Bulk CsEuBr${}_3$ and CsEuCl${}_3$ are experimentally shown to be magnetic semiconductors that order antiferromagnetically at Neel temperatures of 2.0 K and 1.0 K respectively. Given t…
