Abstract
We report on in situ high temperature Fe-57 Mossbauer measurements on several Fe:YBaCuO samples with different Fe concentrations under contr olled oxygen partial pressures. The results are discussed in terms of the temperature dependent binding of oxygen in Fe-rich clusters which differs from that in their more Cu-rich surrounding.
