Abstract

The magnetic responce of LaSrCuO and BiSrCaCuO single crystals has been investigated under quickly varying applied magnetic field. Sharp repetitive jumps in the magnetization vs. field curve were observed and studied as a function of the magnetic field sweep rate. The effect is interpreted as an avalanche - like flux flow, caused by a run-away break of the superconductor stability and the transition from isothermal to adiabatic limit of the flux propagation.
