Abstract
Magnetization measurements on a Pr1.85Ce0.15CuO4-y single crystal (T-c = 19.2 K) have provided evidence of strong field-induced diamagnetic fluctuations near the superconducting transition; the critical zone re presents an important fraction (>33%) of the reversible diamagnetic re gime, at any field above 0.05T. The high-field magnetization displays scaling behaviour and the observed scaling functions are in excellent agreement with the predictions for 2D superconducting systems.
