摘要：

This work is part of an European research programme (HITEMAG) and we report on the high temperature magnetic properties of Sm(CobalFevCuyZrx)(z) sintered magnets. The effects of copper and zirconium in dependence on the Z-value have been studied. At room temperature, both, a higher Zr and/or higher Cu content, increases the useful Z-range with respect to coercivity. An increase in Sm content leads to the best coercivities at high temperatures (450-550degreesC: mu(0) H-J(c) = 0.8-0.45 T). Higher zirconium content shifts the maximum coercivity to lower samarium levels. (C) 2002 Elsevier Science B.V. All rights reserved.
