对氟钙钛矿晶体AMF3:Fe3+(A=K,Rb,Cs;M=Zn,Cd)四角对称占位的零场分裂(ZFS)进行分析,证实了晶格缺陷及畸变的存在.对ZFS参量随晶格畸变参量的变化关系进行了详细研究,考虑了缺陷及缺陷引起的晶格畸变两者的贡献,得出几种氟钙钛矿晶体的晶格畸变参量The zero field splitting (ZFS) of Fe3+ ions at the tetragonal symmetry sites in the fluoroperovskites AMF3 doped with Fe3+ is analysed and shown the existence of the crystal defects and lattice distortion.The ZFS parameters are investigated as a function of the defect induced lattice distortion parameters.The distortion parameters are obtained by adjusting them to fit the experimental ZFS data.
