ABSTRACTThe structural, magnetic and electrical properties of EuBa2Cu3O7-δ have been investigated both for bulk ceramics and screen printed thick films. The bulk ceramic reaches zero resistance at 92 K, and has large intragranular critical current density inferred from magnetization loops; the directly measured critical current density is substantially lower because of the weak links (Josephson junctions) between grains. Screen printed thick films on strontium titanate have poor magnetic and resistive transitions with evidence for two phases. High temperature oxygen anneals produce a bulk ceramic with significantly enhanced magnetic properties.

Critical Current Density Jc

AbstractMeasurements of the critical current density Jc for ultrathin YBa2Cu307‐X (YBCO) films are presented.A high Jc value at 77K in zero field of 2xl06A/cm2 was obtained in a 30nm thick film and even a 5nm thick film could carry a supercurrent of 3.5x105 A/cm2 at 4.2K in zero field. A very weak field‐dependence of Jc was observed when the field was in the (a,b) plane showing greatly depressed dissipation.
