Abstract

The properties of sintered Nd-Fe-B magnets containing 0-6 at.% of Dy and Tb substitutions for neodymium were studied at elevated temperature (300-420 K). Both elements very effectively enhance the coercivity and also decrease both temperature coefficients of spontaneous magnetization and of the sintered Nd-Fe-B magnets. Factors involved in the temperature decadence of hard magnetic properties of the sintered Nd-Fe-B magnets are discussed (author). 18 refs, 5 figs.
