Abstract

Sintered magnetically hard materials with compositions (Nd0.5 − x Pr x Dy0.5)18(Fe0.7Co0.3)remB5.5 (x = 0.12 − 0.5) and (Nd0.6 − x Pr x Dy0.4)15(Fe0.8Co0.2)remB6 (x = 0.03 − 0.4) are studied. The role of praseodymium (at invariable content of dysprosium and cobalt) in the change of magnetic properties of the material (residual induction, coercive force, temperature stability) is determined. The phase composition of the material is identified. The role of praseodymium in the magnetic properties of the material is interpreted.
