Abstract :
In this paper, Co-Zr melt-spun ribbons were prepared and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and vibrating sample magnetometer (VSM). The Co-Zr ribbons showed a coercivity of 120 kA/m. This suggests that the hard magnetic phase in the Co-Zr alloys is not the Co/sub 11/Zr/sub 2/ phase but the Co/sub 5/Zr phase and the coercivity of the melt-spun ribbon increased and then decreased as the annealing temperature increases.
