Abstract
We have investigated the variation of the annealing treatments on T-c and the normal state resistivity R(T) of high quality (001) oriental e pitaxial YBCO films deposited by DC magnetron sputtering. The annealin g treatments in oxygen can completely restore the films properties sup pressed by deoxygenation in vacuum at 500-700 degrees C. A dramatic ch ange is observed in these transport properties without oxygen deficien cy,which may be explained by the influence of the apical oxygen state. (C) 1997 Academic Press Limited.
