Abstract

The need to manufacture permanent magnets based on rare-earth metals of complex shape and with increased thermal stability of magnetic properties forces the use of heavy rare-earth metal dysprosium and transition metal cobalt in the chemical composition of the alloy. In this regard, the phase composition of the permanent magnet material changes. The study of the magnetic properties of secondary phases and their contribution to the magnetic properties of permanent magnets is necessary to find the optimal composition that allows to obtain permanent magnets with the necessary level of properties.
