Abstract:
Systems with compositions Nd60Fe30Al10-xTix and Nd60Fe30Al10-xVx (x=2, 4, 6, 8, and 10)
have been prepared by arc melting and copper mold suction-casting. The cast surface of the samples is
partially crystalline. At increasing the Ti or V content, the crystalline fraction in the samples increases and
for x=10, the alloys are fully crystalline. Melting temperatures also increase with increasing Ti or V content
in the samples. All samples, some of them in a partly crystalline state, exhibit good hard magnetic properties
at room temperature. With increasing Ti or V content, the magnetization continuously decreases, whereas
both the coercivity and the Curie temperature increase. Thermomagnetic curves measured for all samples at
low field exhibit an interesting shape. The temperature dependence of the coercivity of the samples has been
determined. ?? 2003 Published by Elsevier Science B.V.
