摘要

This work validates both inverse and conventional magnetocaloric effects-(MCEs) by simulating the MCE of Ni50Mn37Sn13 using a phenomenological model-(PM) at temperatures between 5 and 350 K. Remarkably, magnetic entropy change-(∆SM) maximizes at the antiferromagnetic transition, reaching 18 J/kg.K. This suggests that PM is a useful technique to study large inverse MCE. The results show that PM is a useful model for analyzing the MCEs of Ni50Mn37Sn13 alloy both conventionally and in reverse, saving a significant amount of time and effort. Ni50Mn37Sn13 is a desirable alloy for cooling technologies due to its low cost and exceptional efficiency throughout a wide temperature range, including room temperature. Most significantly, some of the Ni50Mn37Sn13’s magnetocaloric characteristics are better than, or at least on par with, those of the relevant published studies.
