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.
