Description
Moessbauer emission spectroscopy of the 57Co (57m Fe) isotope has shown that the impurity iron atoms appearing at the CuO-lattice cation sites after the decay of 57Co2+ are donors and can stabilize in two charge states, 57mFe3+ and 57mFe2+, and that the population ratio of these states depends on the Fermi level, whose position is governed by native CuO-lattice defects. A satisfactory agreement between the calculated and experimental values of the quadrupole splitting in Moessbauer spectra has been obtained for the 57mFe3+centers. (author)
