Descripción
<math>^{57}\,\!Fe</math> Mössbauer Spectroscopy measurements were made on the <math>YBa_2(Fe_xCu_{1-x})_30_y\,\!</math> superconducting compounds, for the Fe concentrations of 0.1%, 0.5%, 3.0% and 10%. The Mössbauer spectra, obtained at room temperature and at 4.2 K, are dependent on concentration and show several doublets that can be related to different Cu sites, to the number of oxygen vacancies, and to the presence of a high temperature tetragonal phase. This analysis is based on the values of the quadrupole interactions and on the ratio of the absorption areas. Two Mössbauer doublets in the dilute samples (up to 1.0% Fe) are associated to <math>^{57}Fe\,\!</math> in the <math>Cu_1\,\!</math> site of the compound.
