| Outline of Final Research Achievements |
Recently, a cooling-induced shape memory effect was reported by our research group in a Co-based Heusler alloy system. However, within the Co-based Heusler alloys, there are few reports on the thermoelastic martensitic transformation behavior, which is a vital phenomenon for the realization of shape memory effect. In this research, we developed a novel Co-V-Ga shape memory alloy showing thermoelastic martensitic transformation. Furthermore, in a limited composition range, an anomalous martensitic transformation behavior was found, where the magnetism was observed greatly changes during the martensitic transformation.
