Abstract

High-efficiency and environment-friendly magnetic refrigeration, as a replacement to conventional gas compression, has drawn increasing attention. In this article, polycrystalline TmCoSi and TmCuSi compounds were successfully synthesized and giant low field magnetocaloric effect (MCE) was investigated. Under field change of 0–1 T, (-ΔS_M)_max of 12.0 J/kg K and 8.7 J/kg K and (ΔT_ad)_max of 6.2 K and 3.7 K were obtained at low temperatures for TmCoSi and TmCuSi compounds, respectively. It could be considered as one of the best low-temperature MCE materials compared with reported ErMn₂Si₂ compound showing (-ΔS_M)_max and (ΔT_ad)_max of 14.7 J/kg K and 2.5 K respectively. Furthermore, a low-field and reversible giant MCE around the boiling point of liquid helium with the negligible thermal and magnetic hysteresis indicates that TmCuSi and TmCoSi compounds could be potential candidates of magnetic refrigeration for liquid helium temperature region.
