摘要: Ni–Mn–X Heusler-type alloys (X: group IIIB–VB elements) undergo martensitic transformations, and many of them exhibit magnetic shape-memory field-induced effects, one the most predominant being inverse magnetocaloric effect. To understand cause effect, which involves a entropy increase with applied field, it is necessary to nature coupling in temperature vicinity transition.We present results on neutron polarization analysis experiments Ni–Mn-based Heusler systems, we show that around M
