AbstractMagnetic studies were performed on the high temperature superconductor Tl2Ca2Ba2Cu3O10 (Tc = 123 K) in the form of a grain aligned composite. Investigations with the magnetic field applied parallel and perpendicular to the sample's cannon c-axes were analyzed to obtain the magnetic penetration depth as a function of temperature and the critical current density Jc(H,T).

AbstractThe variations of critical current density Jc of narrow Y‐Ba‐Cu‐O films as a function of temperature and magnetic field are investigated. Films with thickness of 150‐200 nm and width of 20‐100 urn were prepared by laser ablation and laser etching. For t (=T/TC) < 0.75, the temperature dependence of Jc shows a (1‐1) linear behavior, in sharp contrast to that of a Josephson junction. Near Tc, Jc varies with (1‐ t)n where n=3/2 or 2 depending on the morphology of films. The magnetic field dependence of Jc above a characteristic field value Hc’ can be described by a model based on flux creep.
