E. Baggiosaitovitch et al., HYPERFINE INTERACTION AND ELECTRONIC-STRUCTURE OF FE(LA,R)(1.85)SR0.15CUO4, Physica. C, Superconductivity, 235, 1994, pp. 865-866
Samples of (La1-xGdx)(1.85)Sr0.15CuO4 (0 less than or equal to x less
than or equal to 1.0) with 1% of Cu substituted by Fe, were studied at
room temperature by Mossbauer spectroscopy and x-ray diffraction meas
urements. The analysis of the data as a whole allows an interpretation
of the different Fe-species in terms of local surroundings characteri
stic of T, T and T'-phases.
