We investigate the exchange bias ( EB ) phenomenon in the layered manganese oxychalcogenides La 2 O 3 Mn 2 Se 2 . The spin canting of the antiferromagnetic ( AFM ) background leads to the ferromagnetic ( FM ) contribution and the exchange coupling at the FM / AFM interface is responsible for the EB phenomenon. Due to the subtle equilibrium of the magnetic states, the EB field shows strong temperature and cooling field H FC dependences. These results suggest that the EB effect in La 2 O 3 Mn 2 Se 2 could be tuned by H FC and temperature, which is important for designing related devices.
