Influence of the Jahn–Teller effect on magnetic anisotropy in single crystals of fluorine hexahydrates of transition metals

The magnetic properties of fluorine hexahydrates of transition metals have been studied. It was found that the presence of spin-orbit interaction of the transition metal ion has a significant effect on anisotropy of magnetic properties. Depending on the direction of interaction of the orbital magnetic moment of a transition metal cation with a crystal field easy direction of magnetization changes from the crystallographic $b$-axis to the $c$-axis.
