Abstract

Fe3B is a metastable high temperature phase and exists in orthorhombic and tetragonal structures. Here, we report on synthesis, structural and magnetic properties of tetragonal (P42/n) Fe3B stabilized by a very small substitution of Mo (1–3 at.%) for Fe. The (Fe0.98Mo0.02)3B compound possesses a high Curie temperature of 780 K and high saturation magnetization of 175 A·m2/kg (1.60 T). Magnetocrystalline anisotropy field of around 0.8 T and anisotropy energy of 340 kJ/m3 have been determined for magnetically-oriented fine particles of (Fe0.98Mo0.02)3B.
