The exchange bias effect is observed in a diluted magnetic system synthesized with 5% volume fraction of Co3O4 anchored on reduced graphene oxide (rGO) sheet below the antiferromagnetic transition temperature of Co3O4. The glassy magnetic phase below 5 K has been established by relaxation memory studies performed in ZFC protocol.
