| Abstract: | We report on “in situ” high temperature57Fe Mössbauer measurements on several57Fe: YBaCuO samples under vacuum and various controlled temperatures. The results obtained allowed us to get information about the mechanism of oxygen desorption under various annealing heating conditions. |
