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.

## Magnetization measurements of the intragranular pinning force in polycrystalline YBa2Cu307\_ ~ and YRa2(CUl\_xMx)307\_~, where M = Fe,Ni, address two major questions of flux pinning: 1, what are the dominant pinning sites; and 2, what is the relevant pinning mechanism in these materials. It is
