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 intragranular critical current density JΒ’, the apparent pinning potential U0, and the irreversibility temperature Ti~ of meltgrown (MG), quench-melt-grown (QMG), and sintered YBa2Cu306Γ·y (123) were studied. A systematic increase in Uo and a slower drop in Jc with temperature and magnetic field h
