Abstract

Magnetic field-induced martensitic transformation was realized in Ni50-x Cox Mn39 Sb11 alloys. The partial substitution of Co for Ni has turned the antiferromagnetically aligned Mn moments in the starting material Ni50 Mn39 Sb11 into a ferromagnetic ordering, raising the magnetization at room temperature from 8 emug for NiMnSb to ∼110 emug for Ni41 Co9 Mn39 Sb11. In the same quaternary sample, a magnetization difference up to 80 emug was measured across the martensitic transformation, and the transformation temperature (T0 =259 K) could be lowered by 35 K under a field of 10 T. Also a magnetoresistance over 70% was observed through this field-induced transformation.
