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.

TlBaCaCuO thick films were fabricated by the method of screen printing. Zero resistance temperature of 110 K–118 K and critical current density of about 102 A/cm 2 at 77 K were obtained. The thickness of the film was about 30 μm. Using the thick film we have fabricated three-dimensional DC SQUID. The flux modulated V–I curve, V–H curve, and triangular patterns in response to flux applied at the different dc bias current were measured. The results showed that not only TlBaCaCuO thick film DC SQUID was like that from TlBaCaCuO thin film in good microwave behaviour but also the processes of fabricating thick film DC SQUID were easy.
