摘要

The phenomenological model (PM) is implemented to predict the magnetocaloric effect (MCE) of Ni47Mn40Sn13 at temperatures between 4 K and 330 K, confirming both those inverse and conventional MCEs. The results demonstrate that PM is a practically sound model to analyze the MCEs of the Ni47Mn40Sn13 alloy both conventionally and in reverse, saving high efforts and time when calculating MCE. Because Ni47Mn40Sn13 is inexpensive and exhibits remarkable efficiency over an extensive temperature range, including room temperature, it is an attractive alloy for cooling technology. Whenever predicting the MCE of magnets with different types of magnetic transitions, the PM is unquestionably useful.
