Observation of enhanced exchange bias behaviour in NiCoMnSb Heusler alloys
Observation of enhanced exchange bias behaviour in NiCoMnSb Heusler alloys
We report the observation of large exchange bias (EB) in Ni50−xCoxMn38Sb12 Heusler alloys with x = 0, 2, 3, 4, 5, which is attributed to the coexistence of ferromagnetic (FM) and antiferromagnetic (AFM) phases in the martensitic phase. The phase coexistence is possibly due to the supercooling of the high …
