We study the histor)-dependence of diamagnetic response of superconducting Laa.sSr 2CuO4 ceramics in a magnetic field. In this material the granulas are weakly coupled by Josephson junctions, and these couplings are frustrated by the magnetic field. We separate the magnetic response due to intergran
