High-quality, c-axis-oriented thin films of the intermetallic superconductor YNi{sub 2}B{sub 2}C were obtained {ital in situ} by magnetron sputtering on MgO and other substrates held at about T=800{degree}C. The best films showed a maximum of T{sub c}=15.1 K with {Delta}T{sub c}{approx}0.1 K. We report on structural and electrical film characterization including dc resistivity measurements up to 450 K as well as critical-field and critical-current measurements. Scanning tunnel microscope tunneling measurements were also performed, giving further evidence of the overall BCS nature of these compounds. {copyright} {ital 1997} {ital The American Physical Society}
