Abstract 57Fe and151Eu Mössbauer spectroscopy and X-ray diffractometry measurements were performed with europium and iron containing Tl2(Ca0.8Eu0.2)Ba2(Cu0.98Fe0.02)2O8 and EuBa2Cu3O7-d high temperature superconductor samples in order to study the effect of europium incorporated in a Tl-containing high temperature superconductor. Significant differences have been found between the57Fe Mössbauer spectra of Tl-containing samples with and without Eu or between the151Eu Mössbauer spectra of Tl-containing and 1-2-3 type superconductors. The results can be interpreted by assuming that Eu can be localized at the Ca site in the Tl-containing superconductor.
