Room-Temperature Magnetic Order in Air-Stable Ultrathin Iron Oxide.

Room-Temperature Magnetic Order in Air-Stable Ultrathin Iron Oxide. Manual assembly of atomically thin materials into heterostructures with desirable electronic properties is an approach that holds great promise. Despite the rapid expansion of the family of ultrathin materials, stackable and stable ferro/ferri magnets that are functional at room temperature are still out of reach. We report the growth of air-stable, transferable ultrathin iron oxide crystals that exhibit magnetic order at room temperature. These crystals require no passivation and can be prepared by scalable and cost-effective chemical vapor deposition. We demonstrate that the bonding between iron oxide and its growth substrate is van der Waals-like, enabling us to remove the crystals from their growth substrate and prepare iron oxide/graphene heterostructures. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nano letters Pubmed
