“…It is known that the Fe moment of a given Fe-based alloy decreases upon alloying with heavy RE element due to the hybridization of the Fe 3d and the RE 5d states. 28,32 According to Annouar et al, 32 the substitution of Fe by Dy in Fe-Dy-B MGs increased the 5d-3d hybridization. In accordance with that, the decreasing jDS pk M j with increasing Dy content mainly stems from the decrease in Fe moment of this alloy series.…”

The effects of heavy rare earth (RE) additions on the Curie temperature (T C) and magnetocaloric effect of the Fe-RE-B-Nb (RE ¼ Gd, Dy and Ho) bulk metallic glasses were studied. The type of dopping RE element and its concentration can easily tune T C in a large temperature range of 120 K without significantly decreasing the magnetic entropy change (DS M) and refrigerant capacity (RC) of the alloys. The observed values of DS M and RC of these alloys compare favorably with those of recently reported Fe-based metallic glasses with enhanced RC compared to Gd 5 Ge 1.9 Si 2 Fe 0.1. The tunable T C and large glass-forming ability of these RE doped Fe-based bulk metallic glasses can be used in a wide temperature range with the final required shapes. V
