Title: Phase diagram and magnetocaloric effects in Ni{sub 50}Mn{sub 35}(In{sub 1−x}Cr{sub x}){sub 15} and (Mn{sub 1−x}Cr{sub x})NiGe{sub 1.05} alloys

Abstract

The magnetocaloric and thermomagnetic properties of Ni{sub 50}Mn{sub 35}(In{sub 1−x}Cr{sub x}){sub 15} and (Mn{sub 1−x}Cr{sub x}) NiGe{sub 1.05} systems for 0 ≤ x ≤ 0.105 and 0 ≤ x ≤ 0.1, respectively, have been studied by x-ray diffraction, differential scanning calorimetry, and magnetization measurements. Partial substitution of Cr for Mn in (Mn{sub 1−x}Cr{sub x})NiGe{sub 1.05} results in a first order magnetostructural transition from a hexagonal paramagnetic to an orthorhombic paramagnetic phase near T{sub M} ∼ 380 K (for x = 0.07). Partial substitution of Cr for In in Ni{sub 50}Mn{sub 35}(In{sub 1−x}Cr{sub x}){sub 15} shifts the magnetostructural transition to a higher temperature (T = T{sub M} ∼ 450 K) for x = 0.1. Large magnetic entropy changes of ΔS = −12 (J/(kgK)) and ΔS = −11 (J/(kgK)), both for a magnetic field change of 5 T, were observed in the vicinity of T{sub M} for (Mn{sub 1−x}Cr{sub x})NiGe{sub 1.05} and Ni{sub 50}Mn{sub 35}(In{sub 1−x}Cr{sub x}){sub 15}, respectively.
