The exchange bias phenomena of phase-separated Nd1-xSrxCoO3(x=0.10, 0.15) samples were systematically
investigated in this paper. The samples were prepared using conventional solid state reaction method. When the Nd1-xSrxCoO3 samples cooled down in magnetic field below freezing temperature, the hysteresis loops shifted along the
magnetic field axis. Moreover, exchange bias of Nd1-xSrxCoO3 is strongly dependent on the field and the temperature. The
influence of magnetic field on the relative ratio of the coexisting phases may be responsible for these behaviors.
Therefore, our study confirmed that in phase-separated system, the exchange coupling at the interface between the
ferromagnetism clusters and the spin glass regions may induce interfacial exchange anisotropy.
