Abstract: Anomalous temperature dependences of the lower critical fields H(C1)(T) for H parallel-to c measured in YBa2Cu3Ox by the extrapolation method, the superconducting gaps DELTA(parallel-to) and DELTA(perpendicular-to) measured in Bi2Sr2CaCu2O8+x by Raman spectroscopy in two different polarizations parallel and perpendicular to the CuO2, sheets, and the scaling behavior of the Bi1.7Pb0.3Sr1.9CaCu1.908+x magnetoresistance arising from giant fluctuations in the decoupled quasi 2D CuO2 superconducting planes are analyzed in terms of the models taking into account the layered structure of the 2212 and 123 cuprates with a very weak coupling between the CuO2 planes. The importance of the proximity induced superconductivity in explaining unusual H(C1)(T), DELTA(parallel-to)(T) and DELTA(perpendicular-to)(T) features is emphasized.
