Abstract

Abstract: Fe3 B is a metastable high temperature phase and exists in orthorhombic and tetragonal structures. Here, we report on synthesis, structural and magnetic properties of tetragonal ( P 42 / n ) Fe3 B stabilized by a very small substitution of Mo (1–3 at.%) for Fe. The (Fe0.98 Mo0.02 )3 B compound possesses a high Curie temperature of 780 K and high saturation magnetization of 175 A·m 2 /kg (1.60 T). Magnetocrystalline anisotropy field of around 0.8 T and anisotropy energy of 340 kJ/m 3 have been determined for magnetically-oriented fine particles of (Fe0.98 Mo0.02 )3 B. Graphical abstract:
