"Large Uniaxial Magnetic Anisotropy of Hexagonal Fe-Hf-Sb Alloys";
Crystals, 10 (2020), 430.

We theoretically investigate the electronic and magnetic structure of Fe2Hf. The density
functional theory calculations are shown to produce the negative, easy-plane, magnetic anisotropy
in the hexagonal Fe2Hf. Antimony substitution suppresses the planar magnetization direction and
favors the uniaxial magnetic anisotropy, in agreement with experimental observations. Our study
suggests the possibility of the chemical control of the magnetic anisotropy in Fe2Hf by Sb
substitution, and illustrates the potential of (Fe,Sb)2+xHf1−x Laves phase alloys for the permanent
magnet applications.
