| Summary: | Assessing the validity of the phenomenological model (PM) for the magnetocaloric effect (MCE) in MnFeP2/3Si1/3 is the aim of this study. Our work confirms PM for conventional MCE by simulating the MCE of MnFeP2/3Si1/3 at temperatures between 230 K and 310 K. Interestingly, there is a good degree of precision across the whole temperature range in the agreement between the simulated magnetic entropy change (10.1 J/kg.K) and the reported one. Additionally, MnFeP2/3Si1/3′s relative cooling power is evaluated to be 97 J/kg, and heat capacity change characterization is investigated. By reducing the time and effort required to calculate and measure MCE, these results imply that PM is a trustworthy model for investigating MCE in the sharp magnetic transition. Consequently, the PM is very useful for estimating the MCE of magnets, as the MnFeP2/3Si1/3 sample has a sharp magnetic transition. Consequently, we believe that the PM can also be used for predicting MCE parameters for any magnetic transition. |
