Magnetostructural transition from ferromagnetic orthorhombic phase to paramagnetic hexagonal phase can be obtained by chemically alloying appropriate amount of Fe2Ge into MnNiSi. The magnetostructural transition temperature is tunable in a wide temperature range of about 280 K. Saturation moment of the ferromagnetic orthorhombic phase increases from 2.62 μB/f.u. to 3.17 μB/f.u. with Fe2Ge-doping. The magnetostructural transition is accompanied by a large change of magnetization over 80 Am2/kg under magnetic field of 5 T. Relatively large magnetic entropy changes and working temperature ranges were observed in the vicinity of room temperature. Our findings suggest that MnNiSi-Fe2Ge material system is a promising platform for tunable magnetostructural transition and the associated magnetocaloric effect.
