Influence of copper substitution on the magnetic and magnetocaloric properties of NiMnInB alloys
The structural, magnetocaloric, and thermomagnetic properties of Ni 50.51 Mn 34.34− x Cu x
In 14.14 B 1.01 with x=(0, 1.26, and 2.02) have been studied using room-temperature x-ray
diffraction, differential scanning calorimetry (DSC), and magnetization measurements. The
partial substitution of Cu for Mn was found to shift both the martensitic transition temperature
(TM) and the Curie temperature (TC) to lower temperatures. The values of the latent heat (L=
9.4 J/g) and corresponding magnetic (ΔS M) and total entropy (ΔS T) changes (ΔS M= 22.60 …
