[Formula: see text] bulk metallic glass (BMG) exhibits good glass forming ability (GFA) and excellent magneto-caloric effect (MCE). In order to further improve the GFA and MCE of the [Formula: see text] BMG, we attempted to add small amount of Fe as a replacement of Co in the BMG and obtained [Formula: see text] glassy rod using a traditional suction casting method. The [Formula: see text] BMG shows a better GFA and MCE than the [Formula: see text] BMG. The magneto-caloric behavior of the [Formula: see text] BMG was investigated by studying the field dependence of the magnetic entropy change peak and the refrigeration capacity.
