Thin films of YBazCuaO+x are deposited on MgO substrates via dc magnetron sputter technic. The thicknesses varry between 1Onm and 500nm. The films are patterned by dry etching method. Narrow stripes with widths down to 1 urn are obtained without serious degradation, e.g. Tc,ocf > 85K and Tc < 1.6K.
The field dependences of the critical current, current-voltage characteristics and a.c. susceptibility have been investigated for superconducting YBa2Cu307 films prepared by laser ablation. It was shown that the flux line pinning in polycrystalline high Tc films occurs due to anisotropy of the super
