概要
- 論文の詳細を見る
The photo absorption and the magneto-optic properties of Eu^<2+> in EuF_2 have been calculated and compared with experiments. Various calculations so far done are not complete because all of them neglected some important interactions to make the calculations performable. Here the amounts of all the important interactions have been checked carefully and the calculations have been performed in various ratios of these parameters. It has been shown from the best fit with the experiments that the multipole-multipole Coulomb interaction and the anisotropic exchange interaction between the 5d and 4f electrons cancel out each other which leaves nearly isotropic exchange interaction. The absorption structure in such a case has been shown to be similar to that of Freiser's model in which all the 5d-4f interactions were completely neglected.
