Abstract

Phase formation and magnetic properties of PrFe11.5-xVxTi0.5 compounds (x = 0.5-1.5) and their nitrides have been investigated by X-ray diffraction, differential thermometric analysis (DTA) and magnetic measurements. It is found that PrFe11.5-xVxTi0.5 compounds with ThMn12-type structure can be formed by annealing the as-cast samples in a fairly wide temperature range. The substitution of V for Fe in the compounds results in a decrease of the saturation magnetization and Curie temperature. Upon nitrogenation, the Curie temperature is increased to around739-763 K, the saturation magnetization increases by about 10%, and the anisotropy fields are all larger than 80 kOe. The PrFe11.5-xVxTi0.5Ndelta compounds have excellent intrinsic magnetic properties favorable for permanent magnet materials. The hard magnetic properties of PrFe10.5VTi0.5Ndelta magnets prepared by mechanical alloying technique have been assessed. (C) 1998 Elsevier Science B.V. All rights reserved.
