La2-xSrxCuO4 thin films and multilayers prepared by MBE
Abstract
We report on the realization of La2-xSrxCuO4/La2-ySryCuO4 multilayers and on a study of the superconducting transitions in magnetic field parallel and perpendicular to the c-axis. Measuring the activation energies for thermally activated flux flow, which give information on the correlation volume involved in flux jumps, allows to make an estimate of the interdiffusion at the interfaces. © 1994.
