TLDR
In this paper, a screen printing on alumina and SrTiO3 substrates has been used to construct thin films of high T = 90-94 K superconducting oxides and zero resistance was observed only in a few cases.Abstract:
Thick films of the highT
csuperconducting oxides, LnBa2Cu3O7, Ln = Eu, Y, have been fabricated by screen printing on alumina and SrTiO3 substrates. Conditions for optimum superconductivity behaviour of the films have been established.T
varies from 90–94 K for all the films but zero resistance was observed only in a few cases.read more

Current transport in high- T c polycrystalline films of Y-Ba-Cu-O
TL;DR: Electrical measurements were performed on polycrystalline superconducting films of Y-Ba-Cu-O to explore tunneling effects in the film, revealing that in both films the critical current is proportional to (1-T/T/sub c/)/sup 3/2/ near T/ sub c/,.
