| 摘 要： | 本文用羣论的方法提出一种推广的等效自旋哈密顿HSG,用它来描述晶体中过渡族离子的顺磁共振性质。HSG严格地考虑了空间和时间的对称性质。在一阶微扰计算的近似上,证明自旋空间的不可约张量组TLM(L=0,1,…,2S)可以完全描述基态有2S+1个能级的顺磁离子的行为。本文给出了某些常见点羣对称度的不可约张量的形式。这样求出的HSG和Koster-Statz矩阵完全等价。

| Abstract: | A generalized effective spin-Hamiltonian HSG describing the EPR of transition group ions in crystal is proposed on the basis of group theory. In this method, HSG is considered strictly by the space-time symmetry. In the first order perturbation, the irreducible spin tensors TLM (L=0,1,…, 2S) describe completely the EPR of paramagnetic ions with ground state having (2S + 1) energy levels. Irreducible tensors in several point-group symmetries are presented for convenience of obtaining HSG explicitly. Such a HSG is equivalent to the Koster-Statz matrix. |
