摘要：Driven by the demands of fast-developed quantum-spintronic devices and magnetic tunneling junctions,exploring excellent magnetic insulators,which can func-tion above room temperature and have high symmetry(generally speaking perovskite or perovskite-like struc-ture)to facilitate their integration potential with common single crystal oxide films or substrates as further devices,have drawn special attentions[1-4].Unfortunately.
