Abstract: We predict anomalous atomic-scale 0-π transitions in a Josephson junction with a ferromagnetic-insulator (FI) barrier. The ground state of such junction alternates between 0 and π states when thickness of FI is increasing by a single atomic layer. We find that the mechanism of the 0-π transition can be attributed to thickness-dependent phase shifts between the wave numbers of electrons and holes in FI. Based on these results, we show that a stable π state can be realized in junctions based on high-Tc superconductors with a La2BaCuO5 barrier.
