Abstract: An increase in the cobalt concentration in Pr–Dy–Fe–Co–B alloys leads to the substitution of Co atoms for Fe atoms in the atomic positions, which are the nearest neighbors with the rare-earth metal atoms, and to the formation of a significant number of boron-rich phases. At the highest (limiting) cobalt concentrations, boron can be substituted for the transition metals. As a result, the exchange interaction between magnetic sublattices of the rare-earth and transition metals is weakened. In turn, this leads to a decrease in the contribution from the rare-earth ions to the magnetic anisotropy, the temperature stability of which increases.
