Abstract 151Eu,119Sn and57Fe Mössbauer spectroscopy was used to study high Tc superconductors. Mössbauer spectra of Sn substituted EuBa2Cu3O7−y, YBa2Cu3O7−y and TlBaCaCuO4.5+y as well as of Fe Substituted TlBaCaCuO4.5+y were compared. The Sn and Fe ions replace the regular Cu positions in the YBa2Cu3O7−y and in TlBaCaCuO4.5+y materials, fespectively, while the localization of tin atoms in both the119Sn doped EuBa2Cu3O7−y and TlBaCaCuO4.5+y superconductors is different from that of previous cases. Up to our knowledge, this is the first publication on a Mössbauer study of a Tl-containing superconductor.
