Abstract
Annealing effect on soft magnetic properties of Co_(70.5-x)Fe_(4.5)(Ni, Nb)xSi_(10)B_(15) amorphous alloy has been investigated. Nb addition is effective to improve the permeability and the coercive force while Ni is favorable to increase the remanence. The combined addition of Nb and Ni is effecitive to optimize the permeability and remanence. The change of magnetic properties to annealing temperature is classified by three steps and discussed in terms of the structural relaxation, cluster formation and the crystallization process.
