Magnetic properties, martensitic transition, and exchange bias in Ni 50Mn36Sb14, Ni50Mn 36Sb12Ge2, and Ni50Mn 36Sb12Al2 alloys have been investigated. The results reveal that the martensitic transition temperatures and blocking temperature shift to low temperature for Ge substitution and shift to high temperature for Al substitution. The exchange bias field decreases/increases in case of Ge/Al substitution below blocking temperature. All the results can be ascribed to the increase/decrease of ferromagnetic interaction.
