摘要

The paper presents the results of investigation of magnetic, physico-mechanical and operation parameters of sintered magnets of composition (at. %) Sm0.45Pr0.16Gd0.26Dy0.13(Co0.686Cu0.08Fe0.20Zr0.028Be0.006)7.35 (Sm) Nd12Tb2.6Feocr.Co15Ga0.4B8 (Nd) /at. %/. Magnetic properties of magnets Sm and Nd have the following values: Br (T) − 0.93, 1.04; iHc (kA/m) − 1824, 1440; bHc (kA/m) − 700, 808; (BH)max (kJ/m3) − 162, 208; α (295−495.): −0.010, −0.070. The analysis with the aim to compare the investigated alloys with magnets of RCo5 type has been made (Sm12.5 Gd3.3 Er1.9 Co82.3).
