Role of doped Ru in coercivity-enhanced La${}_{0.6}$Sr${}_{0.4}MnO$_3$ thin film studied by x-ray magnetic circular dichroism

The coercivity of La${}_{1-x}$Sr${}_x$MnO${}_3$ thin films can be enhanced by Ru substitution for Mn. In order to elucidate its mechanism, we performed soft x-ray absorption and magnetic…
