Spin polarization of Ru in superconducting Ba(Fe${}_{0.795}$Ru${}_{0.205}$)${}_2$As${}_2$ studied by x-ray resonant magnetic scattering

M. G. Kim, J. Soh, J. Lang +8

We have employed the x-ray resonant magnetic scattering (XRMS) technique at the Ru $L_2$ edge of the Ba(Fe${}_{1-x}$Ru${}_x$)${}_2$As${}_2$ ($x=0.205$) superconductor. We show that prono…
