Abstract
The development and characterization of a new substrate material GdBa2 NbO6, having moderately low dielectric constant and loss factor at MHz frequencies are reported. It has been found that superconducting YBa2 Cu3O7-delta does not react with GdBa2NbO6 even after a 1:1 volume mixt ure was heated at 950 degrees C for 15 h. The suitability of GdBa2NbO6 as a substrate for YBa2Cu3O7-delta thick films was confirmed by fabri cating a thick film of YBa2Cu3O7-delta on this substrate by screen pri nting which gave a zero-resistivity superconducting transition at T-c( 0)=92 K with a transition width of 2 K.
