Origin of large moments in Mn${}_x$Si${}_{1-x}$ at small x

Michael Shaughnessy, C. Y. Fong, Ryan Snow +3

Recently, the magnetic moment/Mn, $M$, in Mn${}_x$Si${}_{1-x}$ was measured to be 5.0 ${\mu }_B$/Mn, at $x$ =0.1%. To understand this observed $M$, we investigate several Mn${}_x$Si${}_{1-x}$ m…
