摘要：
Resistivity measurements in external applied magnetic field up to 8.5T have been performed on Bi2Sr2CuO6+delta/CaCuO2 superconducting superlattices obtained by MBE. The magnetic field (H) vs, temperature (T) phase diagrams have been determined and the experimental data have been compared with that obtained in the case of Bi2Sr2CuO6+delta thin films deposited with the same technique. A reduction of the anisotropy has been obtained in the case of the superlattices with respect to the case of Bi2Sr2CuO6+delta thin films and a three dimensional behavior has been observed by paraconductivity measurements.
