Abstract The glass-forming ability (GFA) and magnetic properties of the Gd$_{50}$Co$_{50}$-based amorphous alloy with Al addition substitution for Co are investigated. It is found that the GFA and magneto-caloric effect of the Gd$_{50}$Co$_{45}$Al$_{5}$ amorphous alloy are better than Gd$_{50}$Co$_{50}$ amorphous alloy. The maximum magnetic entropy change ($-\Delta S_{\rm m}^{\rm peak})$ and the magnetic refrigerant capacity of the amorphous alloy under a field of 5 T are about 6.64 J$\cdot$kg$^{-1}$K$^{-1}$ and 764 J$\cdot$kg$^{-1}$, respectively. The field dependence of magnetic entropy change meets the one predicted by the mean field theory, which is investigated for a better understanding of the magneto-caloric behaviors of the Gd$_{50}$Co$_{45}$Al$_{5}$ amorphous alloy.
