Abstract
The effect of copper alloying on the coercive force and the residual induction of sintered materials (Pr0.53Dy0.47)13(Fe0.64Co0.36)resCuxB6 (x = 0–3 at %) annealed at various temperatures is considered. The dependences of coercive force HcI and residual induction Br on the copper content are found to be nonmonotonic. This fact is explained by that alloying with copper leads to a change in the phase composition, which is accompanied by an increase in the coercive force and the residual magnetization of the alloy, while a change in the chemical composition and the thickness of intergranular interlayers upon copper alloying leads to a decrease in the values of HcI and Br as the copper content increases.
