We propose a fabrication method of the buffer layers, whose biaxial textures are replicated from an original template tape. The purpose of this method is economical texturing process for coated conductors. At first we prepared a biaxially textured metal tape (TM-tape). Then a sacrifice layer (SA), a buffer layer (BU) and a thick metallic layer (SM) were sequentially deposited on the TM-tape. SA-layer and BU-layer were deposited epitaxially to copy the texture of the TM-tape. SA-layer was dissoluble in water. SM-layer with the textured BU-layer was separated and could be used for a supporting tape for the further growth of a superconducting layer. In this way, it is possible to reuse the original textured TM-tape many times. In this paper, we report the results of our experiments, in which we used a biaxially Ni tape, BaO film, STO film, and a thick Ag film for TM-tape, SA-layer, BU-layer, and SM-layer, respectively. The Ag/STO layers were successfully separated form the Ni tape by dissolving the BaO layer in water. The texture quality of the STO layer was well secured after the separation. (c) 2006 Elsevier B.V.
