The 119Sn-Mössbauer probe substitutes Ru4+ at the RuO2-layers as Sn4+. Mössbauer spectra at 4.2 K show the presence of magnetic correlations due to transferred hyperfine field (Bhf) at the Sn(Ru)-sites for two samples (x=0.09 and 0.20), while it was not observed for Sr2RuO4 (x=2.0). The Bhf softly decreases with x going from 0.09 to 0.2, indicating remaining short-range antiferromagnetic correlations at x=0.2 concentration, where a first structural transition has been reported. In both samples, the transferred Bhf shows a canted magnetic structure.

The spectral analysis suggests that Sn substitutes Ru5+ at the RuO2 layers, and enters as Sn4+. We observe for the 4.2K Mössbauer measurements that an in-plane transferred hyperfine field (hf) exists
