Approach to Ferromagnetism in Amorphous Ni--P--B Alloys.

摘要

Magnetization was measured between 1.7and 300exp 0 K in fields up to 70kOe on splat-cooled Ni--P--B amorphous alloys in the critical concentration range for the appearance of ferromagnetism. The onset of ferromagnetism is attributed to interactions between giant moments. For the composition range investigated,the magnetic contribution is arising mainly from moments of 5to 6mu /sub B/with a Kondo-type characteristic temperature of 1exp 0 K. (ERA citation 01:016747)
