摘要

本文采用平均场模型理论模拟了tfesi和DyFeSi金属间磁性合金的磁热特性。建立了理论磁化率与实验磁化率及磁熵变化曲线的良好一致性。根据平均场预测，在10 T磁场下，TFS和DFS样品的\(RCP\)值分别可达810和779 J.kg−1。

Magnetocaloric Effect Simulation in TbFeSi and DyFeSi Intermetallic Magnetic Alloys Using Mean-Field Model

In this paper, the magnetocaloric in TbFeSi and DyFeSi intermetallic magnetic alloys were simulated using mean-field model theory. A good agreement between theoretical and experimental magnetizations and magnetic entropy changes curves was established. Based on the mean-field prediction, \(RCP\) values can reach 810 and 779 J.kg⁻¹ under 10 T magnetic field for TFS and DFS samples, respectively.
