摘要：

Tailorable magnetic properties and magneto-caloric effect were achieved in the Gd-Co binary amorphous alloys. It was found that the Curie temperature (T-c) of the GdxCo100-x (x=50, 53, 56, 58, 60) metallic glasses can be tuned by changing the concentration of Gd as T-c = 708.8-8.83x, and the mechanism involved was investigated. On the other hand, a linear correlation between the peak value of magnetic entropy change (-Delta S-m(peak)) and T-c(-2/3) is found in the amorphous alloys with a linear correlation coefficients of above 0.992. Therefore, the -Delta S-m(peak) of the Gd-Co binary amorphous alloys under different magnetic fields can be easily tailored by adjusting the composition of the alloy. (c) 2016 Author(s).
