Title: Metastable phase in annealed amorphous Ni /sub 0. 8-x/ Fe /sub x/ B /sub 0. 12/ Si /sub 0. 08/ ribbons: structural and magnetic studies

Abstract

Amorphous Ni /sub 0.8- x / Fe /sub x/ B /sub 0.12/ Si /sub 0.08/ ribbons with 0 < x < 0.16 have been prepared by the single roller technique. The samples were characterized by X-ray and DTA studies. Chemical composition has been determined. Magnetic studies were carried out in the rangee 4.2-300 K with 0.5 < H < 15T and the range 293-800 K with 0 < H < 1 T. The samples crystallized to a f.c.c. Ni-like phase at 446/sup 0/C and developed into complex borides etc. at 496/sup 0/C. Samples were heated at 10/sup 0/min./sup -1/ to just above 446/sup 0/C in order to obtain the f.c.c. phase and then studied. While for x=0 though one has f.c.c. Ni phase it is not magnetic even at 4.2K. However with x=0,024, T /sub c/ sharply rises to 460K then rises progressively with the increase in X as in crystalline Ni-Fe alloys. Both T /sub c/ and magnetization are much lower in crystallized f.c.c. phase as compared to Fe-Ni alloys. The results are discussed.
