Amorphous Y-Ba-Cu-O films prepared by Ar ion sputtering at room temperature have been studied by high-resolution transmission electron microscopy (HRTEM). As-deposited film was composed of a mixture of microcrystallites of YBa2Cu3Ox, YBa2Cu4Ox, Y2BaCuOx and Y2Ba4Cu7Ox phases with the size of 3-5 nm. The produced film was crystallized above 300°C by heating in air. The selective crystal growth of the above four phases was observed upon heating up to 600°C, which was a lower temperature than the general epitaxial growth temperature of Y-Ba-Cu-O film.
