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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
