Abstract： Magnetic characteristics of the as-quenched fully and partially amorphous Al85Ni5Y4Fe2Co2 alloy were measured by VSM (vibrating sample magnetometer). The results show that the magnetization curves of the two alloys pass the origin of coordinates and extend through the first and the third quadrants, no remanence and coercivity were observed. The magnetism of the fully and partially amorphous alloys is all a combination of paramagnetism and diamagnetism. The magnetic susceptibility of the fully amorphous alloy is 2.41×10- 4 and that of the partially amorphous alloy is 2.73×10- 4. The magnetisms of the alloys annealed at 330℃and 390℃ were also tested respectively. The magnetic susceptibility of the linear portion of the magnetization curve increases from 2.53×10-4 to 2.81×10-4 as the annealing temperature rises from 330℃ to 390℃. The hybrid microstructures of the alloys may account for the evolution of the corresponding magnetisms.
