论文摘要
批量的CSEUBR $ _3 $和CSEUCL $ _3 $在实验中被证明是磁性半导体，在NEEL温度分别为2.0 K和1.0 K时，在抗fiferromagnet上订购抗fiferromagnetors。鉴于据报道，据报道，纳米颗粒和CSEUCL $ _3 $的薄膜在类似的温度下订购了铁磁，我们观察到CSEUBR中的防铁磁订单$ _3 $ _3 $和CSEUCL $ _3 $的观察 材料。我们的密度功能理论计算也支持了CSEUCL $ _3 $可以用作可切换磁性材料的结论。
Bulk CsEuBr$_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 that nanoparticles and thin films of CsEuCl$_3$ have been reported to order ferromagnetically at a similar temperature, our observation of antiferromagnetic ordering in CsEuBr$_3$ and CsEuCl$_3$ expands the possible applications of halide perovskites to now include spintronic devices where both ferromagnetic and antiferromagnetic devices can be fabricated from a single material. The conclusion that CsEuCl$_3$ can be used as a switchable magnetic material is also supported by our density-functional theory calculations.
