摘要

We report that a spontaneous strain glass to martensite (STG-M) transition occurs in a Ni_(45)Co_(10)Mn_(20)Ga_(25) ferromagnetic strain glass. The signatures of the spontaneous STG-M transition of Ni_(45)Co_(10)Mn_(20)Ga_(25) ferromagnetic strain glass are stronger than those of Ti_(50)Ni_(44.5)Fe_(5.5) strain glass reported previously. Such a difference is attributed to that the martensitic terminal of the former has larger elastic anisotropy than that of the later. The spontaneous STG-M transition in this ferromagnetic strain glass is due to that the delicate competition between the kinetic limitation and the martensitic thermodynamic driving force changes with temperature.
