| 摘 要： | The spontaneous magnetization of the Ho^3＋ ion in holmium iron garnet （HoIG） single crystals in the temperature range of 4.2-294K along the directions 111], 110], and 100] are calculated, taking into account the effects of six magnetically inequivalent sites occupied by the Ho^3＋ ions based on the quantum theory. The calculated results show that the magnetization of the Ho^3＋ ion in HoIG is obviously anisotropic. The theoretical results ave in agreement with those of experiments. A primary interpretation of the anisotropy of magnetization of the Ho^3＋ ion in HoIG is put forward.

| Abstract: | The spontaneous magnetization of the Ho$^{3+}$ ion in holmium iron
garnet (HoIG) single crystals in the temperature range of
4.2--294\,K along the directions 111], 110], and 100] are
calculated, taking into account the effects of six magnetically
inequivalent sites occupied by the Ho$^{3+}$ ions based on the
quantum theory. The calculated results show that the magnetization
of the Ho$^{3+}$ ion in HoIG is obviously anisotropic. The
theoretical results are in agreement with those of experiments. A
primary interpretation of the anisotropy of magnetization of the
Ho$^{3+}$ ion in HoIG is put forward. |
