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 (P4(2)/n) Fe3B stabilized by a very small substitution of Mo (1-3 at%) for Fe. The (Fe0.98Mo0.02)(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 (Fe0.98Mo0.02)(3)B.
