This material is a promising candidate for applications requiring high quality epitaxial insulating layers in YBa2Cu3O7-y thin film circuits: PrBCNO is nearly tetragonal with <2% lattice mismatch to YBCO thus allowing the possibility of epitaxial multilayer growth. Using pulsed laser deposition, we have grown both PrBCNO single films and PrBCNO-YBCO multi-layers; growth conditions typical for YBCO result in highly oriented c-axis PrBCNO films and multi-layers on a variety of (001) substrates. Preliminary measurements show a PrBCNO resistivity > 105 Ω-cm and an optical index of refraction of 2.25 at room temperature for y=l. © 1991 IEEE}, year = {1991}, journal = {IEEE Transactions on Magnetics}, volume = {27}, number = {2}, pages = {1600-1602}, issn = {00189464}, doi = {10.1109/20.133983}, note = {cited By 6}, language = {eng}, }
