Abstract
In-plane penetration depth lambda(ab) was investigated at 45 MHz as a function of de magnetic field H in the Meissner state of Bi2Sr2CaCu2Oy . At low temperatures, lambda(L) changes Linearly with H. With increas ing temperature, a systematic rounding around zero field was observed. These are consistent with a recent theoretical prediction for d-wave superconductors. Together with the study in conventional superconducto rs, it is suggested that the superconducting state of Bi-2212 is uncon ventional.
