Abstract

Oxyanion substitutions at the copper sites can stabilize the Ba free phase YSr₂Cu₃O₇ and allow synthesis to occur under ambient conditions (P.R. Slater and C. Greaves, 1991; P.R. Slater et al., 1993). Here we report in situ ⁵⁷Fe Mössbauer spectroscopy experiments done in Y-Sr-Cu-O related oxides containing sulphate (SO₄^2-), phosphate (PO₄^3-) and borate (BO₃^3-), in the temperature range 300 K ≤ T ≤ 723 K. From the results obtained it has been possible to study the kinetics of oxygen loss, as well as the temperature dependence of the Fe species.
