Abstract

In the present paper, the theoretical simulation and experimental studies of magnetic properties of the Mn0.9Zn0.1CoGe alloy was done. Field dependences of magnetization in a wide range of temperatures were collected. Based on the thermomagnetic Maxwell relation, the magnetic entropy change ΔSM was calculated. Moreover, using the phenomenological model, temperature dependences of magnetization in a wide range of fields were simulated. Values of thermomagnetic properties, such as magnetic entropy change and refrigeration capacity, were calculated.
