Abstract
We report our studies on the fabrication and superconducting properties of thin films in the YBaCuO and BiSrCaCuO systems. The films were manufactured on ZrO2:Y, ZrO2:Gd, MgO, and LaAlO3 substrates, by chemical deposition of properly mixed nitrate precursors, as well as by d.c. magnetron sputtering from a single oxide target. In all cases, as-deposited films required a high temperature heat treatment to become superconducting. After annealing, our films were granular with the thickness ranging from 0.5 to 5 μm, and exhibited sharp superconducting transitions with the zero resistivity state reached at 89 K and 77 K for YBaCuO and BiSrCaCuO films respectively. Patterning techniques, most suitable for our deposition methods, were also developed and tested.
