Patent ID: 8313846

Claim:
A magnetic artificial superlattice comprising laminated thin films of two or more kinds of magnetic flaky particles, the laminated thin films of magnetic flaky particles being magnetic titania nanosheets, obtained by exfoliation of a layer titanium oxide in which Ti atoms in the lattice have been substituted with magnetic elements, wherein the magnetic titania nanosheets are laminated with at least one film sandwiched between the magnetic titania nanosheets, the at least one film being made of an inorganic polymer, an organic polymer, or an inorganic compound comprising a metal complex or a polynuclear hydrate ion, wherein the magnetic elements of respective kinds of the magnetic titania nanosheets are different from each other, and wherein magneto-optical properties of the magnetic artificial superlattice are controllable based on control of optical transition between the different magnetic elements via interlayer interaction of the titania nanosheets.
