Effect of Si and Ga substitutions on the magnetocaloric properties of NiCoMnSb quaternary Heusler alloys
Effect of Si and Ga substitutions on the magnetocaloric properties of NiCoMnSb quaternary Heusler alloys
The effect of Si and Ga substitutions on the magnetic and the magnetocaloric properties in Heusler based system Ni46Co4Mn38Sb12−xZx (Z = Si and Ga) has been studied. From the M(T) plots it is found that Si substitution stabilizes the austenite phase, whereas Ga substitution stabilizes the martensite phase. Strong metamagnetic …
