| The glass forming range, saturation magnetization, coercive force, Curie and crystallization temperatures have been studied for Co-Zr-Nb thin film alloys made by sputtering. The glass forming range it expanded in the middle ratio of Zr and Nb. The relationship of magnetic moment to solute concentration in Cn-Zr, Co-Nb and Co Zr-Nb systems could be correctly interpreted by Friedel`s theory. Coercive force of Co-Zr and Co-Nb alloys correspond to the magnitude of magnetostriction in amorphous region. With increasing solute concentration, the crystallization temperature is increased and the Curie temperature is decreased. The solute concentration which the crystallization temperature is higher than the Curie temperature is about 17 at.%. |
