Abstract The magnetization curves along the crystal axes for Gd$_2$Fe$_{17}$ and Gd$_2$Fe$_{17}$H$_3$ were analysed based on the single-ion model. If the Gd－Fe exchange interaction has been taken as isotropic as usual, the fitted values of magneto-crystalline anisotropy of the Fe sublattices in Gd$_2$Fe$_{17}$ and Gd$_2$Fe$_{17}$H$_3$ would become unreasonably different from those of the corresponding Y or Lu compounds. It was shown that the large difference is caused by the neglect of the anisotropy of the Gd－Fe exchange interaction.

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.
