自旋-自旋相互作用对红宝石零场分裂的贡献

CONTRIBUTION FROM THE SPIN SPIN INTERACTION TO THE ZERO FIELD SPLITTING OF RUBY

本文引入自旋－自旋相互作用，计算了红宝石等３种三角晶体中Ｃｒ３＋离子的零场分裂，理论计算与实验值一致．研究表明。

This paper caculates the zero field splitting D of Cr 3+ in trigonal crystal fields (including ruby) by considering the spin spin interaction for the first time. The theoretical results are in good agreement with experimental values. From the inverstigation, it is shown that the contribution from the spin spin interaction to the zero field splitting of d 3 ions in trigonal fields should not been neglected.
