Giant inverse magnetocaloric effect near room temperature in Co substituted NiMnSb Heusler alloys
Giant inverse magnetocaloric effect near room temperature in Co substituted NiMnSb Heusler alloys
The effect of Co on the structural, magnetic and magnetocaloric effect (MCE) of Ni50−xCoxMn38Sb12 (x = 0, 2, 3, 4, 5) Heusler alloys was studied. Using x-ray diffraction, we show the evolution of the martensitic phase from the austenite phase. The martensitic transition temperature is found to decrease monotonically with …
