Abstract

For the first time the (001)-oriented Sr-based (Hg,Pb)-1223 films have been synthesized using the two-step procedure. Hg-free precursor films with the thickness of 1 μm have been deposited by MOCVD or PLD and then the films were annealed in sealed quartz ampoules together with synthesised (Hg,Pb)-1223 ceramics or a pressed precursor mixture of the same cation composition. No post-annealing in oxygen was used for these films. The phase composition of the PLD-films depended crucially on the deposition temperature of the precursor films. The best MOCVD films contained predominantly (Hg,Pb)-1223 and small amounts of non-superconducting phases according to XRD. The Tc=118 K and jc(77K,0.01T) = 2.5×106 A/cm2were measured for the MOCVD-samples.
