Abstract: The purpose of this work is to refine the experimental study of the magnetocaloric effect in MnNi${}_{1-x}$Fe${}_x$Ge single crystals. Single crystals of MnNi${}_{0.75}$Fe${}_{0.25}$Ge, MnNi${}_{0.8}$Fe$_{0.2}$Ge, MnNi${}_{0.9}$Fe${}_{0.1}$Ge were grown by the Bridgman method, and their magnetic and magnetocaloric properties were studied. It is shown that the magnitude of the inverse MCE strongly depends on the orientation of the single crystal. It is shown that in strong magnetic fields the inverse magnetocaloric effect on the AF-FM transition changes the sign with an increase in the magnetic field above 3 T.
Keywords: magnetocaloric effect, half-Heusler alloys.
