Abstract

The total area of the57Fe Mössbauer spectra of the EuBa2 (Cu0.98119Sn0.0157Fe0.01)3O7-δ superconductor exhibited a highly usual anomalous temperature dependence, i.e. it increased monotonously with increasing temperature between 120 and 300 K. We found also anomalous changes in the57Fe Mössbauer parameters around Tc. These latter changes could be associated with phonon softening and low temperature phase transformation.
