Abstract

Thin films of the new class of high temperature superconducting perov-skites have been prepared by laser ablation of t,he bulk materials with a pulsed, excimer laser operating at 193 nm. The films were deposited on room temperature substrates without post-deposition processing. The existence of superconducting regions in the inhomogeneous films was established by a novel microwave method which uses a slightly modified electron spin resonance spectrometer.
