Abstract
The remanence, coercivity, and maximum energy product of R-Nd-Fe-B (R = Tb, Dy) and NdFe-Co-B alloys were studied in the range-80 to 250°C. Doping of Nd-Fe-B alloys with Tb and Dy was shown to increase coercivity and, accordingly, the temperature coefficient of magnetic induction. The introduction of 7-12 wt % Co raises the Curie temperature of the alloys, thereby improving their thermal stability.1 Ural State University, Yekaterinburg.
