Ag. Chourey et al., SUPERCONDUCTING TRANSPORT-PROPERTIES OF YBA2CU3O7-DELTA FILMS GROWN BY HOLLOW-CATHODE MAGNETRON SPUTTERING, Materials letters, 17(1-2), 1993, pp. 9-12
YBaCuO films were in situ grown using hollow cathode magnetron sputter
ing on substrates having different lattice constants. Transport proPer
ties show that the films grown on lattice matched substrates have high
er critical current densities due to better grain alignment and the co
nsequent reduction in the thickness of the grain boundaries.
