This work is devoted to experimental studies of the magnetocaloric effect in composite
material based on MnAs in pulsed magnetic fields up to 40 kOe using the high-speed
infrared fiber-optic temperature sensor with the simultaneous measurement of the sample
magnetization by the induction method. The maximum values of the magnetocaloric effect
in the samples of the composite material based on MnAs, obtained in the pulsed magnetic
field of 40 kOe, were $\Delta T$ = 7.2 K at T0 = 318:5 K under heating, and $\Delta T$ = 9.4 K at $T_0$
= 314.5 K under cooling. In this case, the maximum energy loss for magnetizing of the
sample in the vicinity of the 1st order phase transition was W = 59 J/kg.
Keywords:
magnetocaloric effect, high magnetic field, MnAs.
