Invention: C-axis oriented high temperature superconductors deposited onto single crystals of gadolinium gallium garnet and method of making the same

Year	Description
1994	Invention patented by Arthur Tauber and Steven C. Tidrow on April 11th, 1994. Abstract: C-axis oriented microwave quality HTSC films are deposited onto single crystals of gadolinium gallium garnet (GGG) using pulsed laser deposition (PLD) with conditions of 85 mTorr of oxygen partial pressure, a block temperature of 730.degree. C., a substrate surface temperature of 790.degree. C. and a laser fluence of 1 to 2 Joules/cm.sub.2 at the target, a laser repetition rate of 10 Hz and a target to substrate distance of 7 cm and in which the a and b lattice parameters of the GGG exhibit a mismatch of less than 2.5 percent with the a and b lattice parameters of the HTSC.
