Abstract:
[(Fe 0.5 Co 0.5 ) 0.75 B 0.2 Si 0.05 ] 96 Nb 4 } 100-x ,y (Gd x , Cu y ) (x = 0.5, 1 and 2), (y = 0.5) alloys with different diameters were prepared by copper mold casting. The structure, the thermal and the magnetic properties were studied by X-ray diffraction, differential scanning calorimetry and vibrating sample magnetometry, respectively. Minor Cu addition completely changes the crystallization behavior, and also the glass-forming ability decreases because of the decrease in the supercooled liquid region. However, the magnetic properties are significantly improved upon annealing because of the precipitation of (Fe,Co) phase. In case of [(Fe 0.5 Co 0.5 ) 0.75 B 0.2 Si 0.05 ] 96 Nb 4 } 100-x (Gd x ) glass, Gd addition does not change the crystallization behavior. In turn, it increases the supercooled liquid region when compared with [(Fe 0.5 Co 0.5 ) 0.75 B 0.2 Si 0.05 ] 96 Nb 4 , but even then the glass-forming ability is reduced (critical glassy diameter d c 〈 1.5 mm). The saturation magnetization of the glass is also decreased with increasing Gd content.
