We present a novel bottom-up fabrication for spin-electronics devices by using a new class of nanomaterial namely, a titania nanosheet derived from a layered titanate by exfoliation. Magnetic and magneto-optical measurements demonstrate that Co-substituted titania nanosheet (Ti0.8Co 0.2O2) acts as a ferromagnetic material at room temperature. We also demonstrate that the careful placements of ferromagnetic nanosheets into thin-film architectures on a microscopic chip allow a rational design and construction of advanced functional devices such as ferromagnetic superlattices, magneto-optical devices.
