In recent years, CoNiGa has emerged as a new FSMA system that can be a potential alternative to NiMnGa alloys [19] . In addition, some compositions exhibit high martensitic transformation temperatures, which make CoNiGa a potential high-temperature SMA system. In this project, we investigated the effect of composition on the transformation behavior as well as phase stability of Co-Ni-Ga based alloys though experimental and computational means. One of the major outcomes of the research is the discovery that in Co-Ni-Ga, the ratio of valence electrons to atoms (e/a) ratio, and the so-called magnetic valence influence the transformation behavior in these systems:
