Magnetic properties of sintered heterogeneous compositions based on alloys of 3d- and 4f- transition metals

The paper presents the results of investigation of the magnetization reversal processes of sintered powder compositions based on micropowders of Nd2Fe14B and Sm(Co0,6Cu0,4)6,0 alloys. Samples were obtained in a high-coercivity state. It is shown that an increase in the volume content of Nd2Fe14B in the composition of the samples under study leads to an increase in the saturation magnetization and to a significant decrease in the coercive force.
