YBa{sub 2}Cu{sub 4}O{sub 8} films were fabricated at atmospheric pressure by the sol--gel method using metal alkoxides. Gel films on Ag substrates, prepared from a heterometallic alkoxide solution, were fired at 800 {degree}C for 10 h to yield highly oriented YBa{sub 2}Cu{sub 4}O{sub 8} films. Simultaneously using both the sol--gel method and Ag as a substrate was found to be remarkably effective for promoting the formation of the YBa{sub 2}Cu{sub 4}O{sub 8} phase and producing highly oriented films.
