Abstract
Screen printed thick film technology is recognised as an inexpensive and effective means for the production of superconductors which have potential applications in the electronics and microwave device industries. Additions of the platinum group metals have been made to superconducting thick films of YBa2Cu3O7-δ, and these have shown significant improvements, relative to melt processed films, in both their superconducting and physical properties, particularly in their critical current densities. A possible mechanism to explain the improvements is discussed.
