Title: Hard magnetic properties observed in bulk Mn 1–xGa x

Here, Mn-Ga binary alloys have shown promising magnetic properties, even though these alloys contain no rare-earth metals. Both theoretical predictions and experimental work showed that nanoscaled Mn-Ga samples, such as thin films could have remarkable magnetic properties. Although the prediction provides a useful guideline and thin films supply us with materials in some application, bulk materials are required for majority of the applications that require a strong magnetic field. We have made bulk Mn 1-xGa x alloys by mechanically milling and heat treatments. In this paper, we report annealed Mn 1-xGa x bulk composites that exhibit coercivity up to 18.8 kOe.
