| Abstract: | Structural differences between the 1-2-3 type and 1-2-4 type high temperature superconductors were studied by comparing their151Eu and57Fe Mössbauer spectra. The similarities between the corresponding Mössbauer parameters of Eu Mössbauer spectra of 1-2-3 and 1-2-4 compounds demonstrate that the Eu state can be considered to be identical in both perovskites. The changes in the Fe Mössbauer parameters of 1-2-4 type superconductor compared to those of 1-2-3 type compound can be associated with structural differences. |
