The critical current density J c and the apparent pinning potential U Γ 0 in a single crystal NdBa 2 Cu 3 O y superconductor which shows a broad peak effect are investigated by measuring a DC magnetization and its relaxation. The field-induced pinning mechanism does not explain the temperature depen
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.
