Abstract

We have investigated the angle and field dependence of the ac susceptibility in Bi2Sr2CaCu2O8 Single crystals at low external fields. The ac field was applied perpendicular to the CuO2 planes. The first and third harmonic of the ac susceptibility exhibit a remarkably sharp transition when the de field component perpendicular to the CuO2 planes crosses a threshold field H-th. H-th is strongly temperature dependent but is independent of the parallel field component. We prove that these structures are related to the irreversibility line and propose a simple model which excellently explains the measurement data.
