[en] We report on the magnetic behavior observed by ¹¹⁹Sn-Moessbauer spectroscopy in Ca_2-xSr_xRuO₄ samples (x=0.09, 0.2, and 2.0). The ¹¹⁹Sn-Moessbauer probe substitutes Ru⁴⁺ at the RuO₂-layers as Sn⁴⁺. Moessbauer spectra at 4.2 K show the presence of magnetic correlations due to transferred hyperfine field (B_hf) 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 B_hf 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 B_hf shows a canted magnetic structure
