Abstract
Magnetization and electrical transport measurements under magnetic fie ld H parallel-to c are reported for L2-xCexCuO4 single crystals. Close to the upper critical field line a broad region is found were field i nduced fluctuations dominate the reversible electromagnetic response o f the crystals. Excellent scalings of 2D nature are found for enhanced diamagnetism and excess conductivity, which in addition allow to extr act a linear H(c2)(T) dose to T(c).
