| 摘 要： | 根据一种统一而简单的计算立方晶体中自旋-晶格耦合系数G_(11)和G_(44)的方法,笔者由d~3离子在四角和三角场中的零场劈裂的高阶微扰公式计算了二价钒离子在石灰中的自旋-晶格耦合系数G_(11)并预言了G_(44)。G_(11)的计算结果和实验值较好地符合,G_(44)的预测值则有待实验检验。

| Abstract: | With a unified and simple method of calculating the spin-lattice coupling coefficients G_(11) and G_(44) for d~n ions in cubic crystals, the author has calculated the coupling coefficient G_(11) and predicted G_(44) for V~(2+) ion in lime from the high-order perturbation formulae of zero-field splitting of d~3 ions in the tetragonal and trigonal symmetries. The calculated value of G_(11) is in good agreement with the experimental value and the predicted value of G_(44) remains to be verified experimentally. |
