Abstract
We have explored the thermal effects of moderate substitutions of cobalt for iron in rapidly solidified, microcrystalline alloys of composition (Fe100−xCox)76Pr16B8, where x=0, 5, 10, 20, and 30. The maximum intrinsic coercivities were about 20 kOe and the saturation magnetizations were about 88 emu/g, both independent of cobalt content. A significant improvement in the Curie temperature of the hard phase is obtained with increasing cobalt content. A similar improvement in the reversible and irreversible temperature behavior is also observed as the cobalt content is increased.Keywords
