Kinetic arrest of the ferromagnetic state in Mn $$_3$$ 3 GaC and Ni $$_2$$ 2 MnGa composite mixtures

Abstract The kinetics of the ferromagnetic to antiferromagnetic transition in Mn $$_3$$ 3 GaC can be arrested and its magnetic properties can be tuned by mixing a small amount ( $$\sim $$ ∼ 10%) of Heusler Ni $$_2$$ 2 MnGa to Mn $$_3$$ 3 GaC. A detailed study of magnetic properties of composite mixt...
