✦ Synopsis

Single crystals of YBaZCu@_d were irradiated at 95 K by 5.6 GeV Xe ions and the evolutions of the superconducting resistive curves -measured parallel and perpendicular to the c axis -were determined in situ as a function of ion fluences. We find that pc and pob increase linearly with the fluence and even tend to saturate for the highest fluences. This behaviour strongly differs from that found for sintered samples irradiated under the same conditions for which a quasi-exponential increase of resistance was observed. Nevertheless our results confirm that energy deposition by electronic excitation plays a role in defect creation as previously reported in Xe irradiated sintered samples.
