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.
