Abstract
The process of magnetic field penetration into polycrystalline high-T c superconductors of the YBa2Cu3O7−x and Bi2Sr2Ca2Cu3O10−x systems has been studied using traditional magnetooptical methods and scanning Hall probe microscopy. It is established that remagnetization of a sample is accompanied by the formation and propagation of a stationary magnetic flux annihilation (MFA) wave. Spatial inhomogeneity of the superconductors studied is manifested by a curvature of the MFA wave front.
