Abstract

In this paper, phenomenological modeling and experimental studies were conducted to predict the magnetocaloric properties of the MnCoGe alloy. The temperature dependence of magnetization was measured and calculated using a simple phenomenological model. A good correlation between simulated and experimentally determined data was observed. The phenomenological model allowed us to reveal theoretical values of the magnetic entropy change, full width at half maximum of ΔSM vs T curve, and relative cooling power.
