| 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 results confirmed the nanocrystalline character of these alloys in the temperature range 550–650 °C. The influence of the uranium content on the structural stability has been observed for annealing treatment at high temperature, i.e. at about 700 °C. The coercive field strongly depended both on the annealing temperature and on the uranium content. A minimum value of Hc was observed after annealing at 550 °C. Core losses of all alloys in the nanocrystalline state decreased with increasing uranium content. © 1998 Kluwer Academic Publishers |
