Depth dependence of itinerant character in Mn-substituted Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>
Depth dependence of itinerant character in Mn-substituted Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>
We present a core-level photoemission study of Sr3(Ru1−xMnx)2O7, in which we monitor the evolution of the Ru-3d fine structure versus Mn substitution and probing depth. In both Ru-3d3/2 and -3d5/2 core levels, we observe a clear suppression of the metallic features, i.e. the screened peaks, implying a sharp transition from …
