Thick films of the high T 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 c onset varies from 90-94 K for all the films but zero resistance was observed only in a few cases. © 1988 Indian Academy of Sciences.
