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.

Hidden Order

Order parameter of non-magnetic phase transition at 105 K, which is called "hidden order", was revealed in spin-orbit coupled iridate Ca5Ir3O12. This discover of order parameter with rotational and directional degrees of freedom in atomic scale will lead to development of energy saving devices with a fast cross-correlated response.
