摘要:

在考虑掺杂晶体局域畸变的影响后, 建立了联系RbMgF3: Ni2+体系的局域畸变结构与EPR谱间的关系, 并计算了RbMgF3: Ni2+晶体在C3vD3d对称下的零场分裂参量和g 因数. EPR谱的理论计算值与实验值符合甚好. 

Abstract:

Taking account of the effects of local distorted structure of the doped crystal, the relationship between the local distorted structure and the EPR parameters was established for RbMgF3: Ni2+ system. The zero-field splitting parameter D and the g factors for Ni2+ ions in RbMgF3 crystals with C3v and D3d symmetry were calculated, and found to agree well with the experimentally measured values.

Key words: electron paramagnetic resonance, local lattice structure, superposition model, RbMgF3Ni2+ crystal
