Аннотация: For more than a quarter of a century, scientists from all over the world have been solving problems for the development and implementation of green technologies. One such area of interest involves the development of alternative refrigeration systems based on the magnetocaloric effect. Currently, the scientific literature comprehensively covers thermodynamic models elucidating static scenarios. However, to simulate the practical cycle in a magnetic refrigerator, kinetics and adiabatic conditions require consideration. To study the kinetics, we used the numerical calculation of the following differential equation dM/dt = −Γ(dF/dM) [1]. In our research, we demonstrate the influence of adiabatic measurement conditions on hysteresis properties. To account for adiabatic conditions, we incorporated sample heating during the application of an external magnetic field. This approach effectively illustrated the significant reduction in hysteresis width observed in the experiment under adiabatic conditions.
