| Popis: | The temperature dependence of the ab plane penetration depth λ ab ( T ) in epitaxial films is reported. λ ab ( T ) has been determined by measuring the critical current versus magnetic field (Fraunhofer pattern) of grain boundary Josephson junctions obtained on a bicrystal substrate. The temperature dependence of λ ab ( T ) from 10 K to 70 K is found to be different from the classical two-fluid model. |
