Query: Topological insulator associated with quantum anomalous Hall phase in
  ferromagnetic perovskite superlattices   We do a search for topological insulators which are associated with
ferromagnetic ordering and show anomalous quantum Hall effect, among transition
metal oxide superlattices taking the parent compounds as LaAlO3 and SrTiO3.
Among the various superlattices which are studied here, (LaAlO3)10/(LaOsO3)2
exhibits a ferromagnetic ground state with a topologically non-trivial energy
gap when a spin-orbit interaction is turned on. The study of transverse
conductivity shows that the system has quantized Hall conductivity inside the
topological energy gap without applying any external magnetic field. The
ferromagnetic order parameters and the ordering temperature (Tc) have been
estimated by taking a simple Heisenberg model of ferromagnetism.
