K. Yamagiwa et I. Hirabayashi, Orientation behavior of REBa2Cu3O7-y (RE = rare earth and Y) films prepared by chemical solution deposition, JPN J A P 1, 39(2A), 2000, pp. 452-457
We have succeeded in preparing REBa2Cu3O7-y (RE123; RE = rare-earth element
s and Y) films by chemical solution deposition (CSD) processing using metal
naphthenates under low oxygen partial pressure. Few reports have been publ
ished on the preparation of RE123 by CSD processing, therefore, we prepared
various RE123 films on different substrates systematically and examined th
e difference in the appearance of a/b-axis oriented grains and their in-pla
ne alignment for each RE123 film as a function of heat-treatment parameters
. Processing temperature and substrate dependencies of these films, grown b
y solid phase epitaxy, were observed to be the same as in the case of vapor
phase epitaxy. Dependencies on ionic radius of RE elements are also observ
ed and it is explained by lattice misfit.
