| The use of high temperature superconductor for device application has made the compatibility of the film and substrate an important issue. Garnets having reasonably low dielectric constant and low dielectric losses can be viable low cost substrate materials for the microwave devices. Garnet single crystals like Gd3Ga5O12 (GGG), Y3Ga5O12 (YGG), Y3Al5O12 (YAG) etc. can be potential HTSC substrate materials for microwave devices. Properties of HTSC films on some of these garnet crystals are compared here. |
