The magnetocaloric effect in TbNi2 alloy ribbons synthesized by rapid solidification was investigated. This material crystallizes in a superstructure of the cubic Laves phase structure type C15 (space group F-43m). The saturation magnetization and Curie temperature are MS = 134 ± 2 A m2 kg−1 and TC = 37 ± 1 K, respectively. For a magnetic field change of 5 T, the material shows a maximum magnetic entropy change |ΔSMpeak| = 13.9 J kg−1 K−1, with a full-width at half-maximum δTFWHM = 32 K, and a refrigerant capacity RC = 441 J kg−1. The RC value is similar to those reported for other magnetic refrigerants operating within the temperature range of 10-80 K. Finally, it is worth noting that the use of rapid solidification circumvents the necessity for long-term high-temperature homogenization processes normally needed with these RNi2 alloys.
