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