Title: Effects of the partial substitution of Ni by Cr on the transport, magnetic, and magnetocaloric properties of Ni 50Mn 37In 13

Here, the structural, magnetic, and magnetotransport properties of Ni 50-xCr xMn 37In 13 Heusler alloys have been synthesized and investigated by x-ray diffraction (XRD), field and pressure dependent magnetization, and electrical resistivity measurements. The partial substitution of Ni by Cr in Ni 50Mn 37In 13 significantly improves the magnetocaloric effect in the vicinity of the martensitic transition (T M). This system also shows a large negative entropy change at the Curie temperature (T C), making it a candidate material for application in a refrigeration cycle that exploits both positive and negative magnetic entropy changes. The refrigeration capacity (RC) values at T M and T C increase significantly by more than 20 % with Cr substitution. The application of hydrostatic pressure increases the temperature stability of the martensitic phase in Ni 45Cr 5Mn 37In 13. The influence of Cr substitution on the transport properties of Ni 48Cr 2Mn 37In 13 is discussed. An asymmetric magnetoresistance, i.e., a spin-valve-like behavior, has been observed near T M for Ni 48Cr 2Mn 37In 13.
