چکیده انگلیسی
Magnetic behavior of B2-type Co1âcFec alloys (0.4â¤câ¤0.6) is studied as functions of composition and quenching temperature. Obtained mean magnetic moment shows increase with composition up to câ0.52 and then changes its slope. Furthermore, the moment decreases with quenching temperature in the B2-phase region, while it remains constant in the A2-phase region. The relation between the observed magnetic moment and the point defect properties is discussed. As a result, the change in the magnetic moment is found to be proportional to the square of the long-range order parameter. This relation is explained by noting the magnetic moment on Fe atom, which is assumed to depend on the number of nearest neighbor Co atoms.
