Abstract Mn2CrGa is a newly found Heusler compound with most of its properties remain unknown. We investigated this system using first-principles calculation and found that it can show a martensitic transformation with a highly ordered L21 structure. However, the experimental results of melt-spun Mn2CrGa ribbons show a disordered A2-type structure which tends to decompose into D019 and D03-type phases during annealing. These characters prohibit the predicted martensitic transformation from happening. This system also shows interesting features like relatively high Curie temperature and strong magnetic interactions, which deserve further studies.
