Abstract :
In the present study, we focus on the related material of Mn2CoGa, which has been already reported to indicate half-metallic density of states from theoretical calculations, because the single phase is easily obtained down to low temperatures. Magnetic and powder ND measurements were made in the Mn2CoGa alloy, and high angle annular dark field-scanning transmission electron microscopy (HAADF-STEM) observations were complementally carried out.
