Abstract
The influence of annealing on the structure and some magnetic properties of Fe73.5Cu1Nb3-xUxSi13.5B9 (x = 1, 2, 3) alloys has been studied. The result s confirmed the nanocrystalline character of these alloys in the temperatur e range 550-650 degrees C. The influence of the uranium content on the stru ctural stability has been observed for annealing treatment at high temperat ure, i.e. at about 700 degrees C. The coercive field strongly depended both on the annealing temperature and on the uranium content. A minimum value o f H-c was observed after annealing at 550 degrees C. Core losses of all all oys in the nanocrystalline state decreased with increasing uranium content. (C) 1998 Kluwer Academic Publishers.
