| 摘 要： | 本文根据晶场理论用点电荷近似计算了Zn2-W六角铁氧体七个晶位(2d,4e,4fⅣ,4fⅥ,6g,12k和4f)Fe3+离子的单离子各向异性。结果正如我们所预期的,各个晶位都有一定贡献,且既有正的贡献,也有负的贡献,能够解释对Zn2-W作离子置换的实验结果。关键词：

| Abstract: | Single ion anisotropy of Fe3+ ions at each site of the 7 sublattices (2d, 4e 4fⅣ,4fⅥ, 6g, 12k and 4f) in the hexagonal ferrite Zn2-W has been calculated by crystal field theory using point charge model. As expected, the results show that the contributions of diffrent sites are different and may be either positive or negative, thus the experimental results of substituted W-type ferrites can be explained. |
