Kurzbeschreibung (Abstract)
We study the dependence of the magnetocaloric effect on the magnetic field-change-rate the first order magnetostructural transition in Mn3GaC by measuring the adiabatic temperature change Delta T at three different time scales: 11mTs(-1), 700mTs(-1), and similar to 1000Ts(-1). We find that the maximum adiabatic temperature-change of about 5 K is reached in the 11mTs(-1) and 700mTs(-1) rates, whereas for the similar to 1000Ts(-1)-rate the transition lags the change in the magnetic field so that the maximum adiabatic temperature-change is not attained.
