Title: | Electrodeposited films of YBa2Cu3O7−x on Ag and on SrTiO3: a comparison |
Authors: | Martín-González, Marisol; Alario-Franco, Miquel Á.; Morán, Emilio | Issue Date: | Nov-2000 | Publisher: | Elsevier | Citation: | Physica C 341-348(4): 2375-2376 (2000) | Abstract: | Thick films (~ 30μ) of YBa2Cu3O7−x (YBCO) have been obtained through cationic electrodeposition on silver and on reduced SrTiO3, so as to make it conducting and eliminate the need for a conducting buffer layer (Spanish patent P9802655). The superconducting films morphology is, in both cases, of a columnar type, as shown by SEM, leaving some empty spaces in between the columns. These spaces can be diminished, when silver is used as a substrate, by a multiple sequential electrodeposition. Although the films are then not continuous, critical temperatures are as high as usual ( 92 K) and critical currents (as determined by the Bean method) are, in A/cm2, respectively 9 500 for YBCO/Ag and 3 250 for YBCO/SrTiO3. | Description: | 2 páginas, 3 figuras. | Publisher version (URL): | http://dx.doi.org/10.1016/S0921-4534(00)01266-1 | URI: | http://hdl.handle.net/10261/31243 | DOI: | 10.1016/S0921-4534(00)01266-1 | ISSN: | 0921-4534 |
