Abstract
The high-temperature coercivity of mechanically alloyed and subsequently annealed RCo 5 (R = Sm and Y) is studied. The annealed materials have the hexagonal CaCu 5 structure with 2:17 (or 1:7) regions as a minor phase, High-temperature magnetic measurements show that the coercivities of materials decrease with increasing temperature from room-temperature to 873 K, but that the temperature coefficient of the coercivity of YCo 5 is much smaller than that of SmCo 5. This behavior is explained in terms of the intrinsic temperature variation of the magnetocrystalline anisotropy.
