Epitaxial Patterning of Bi2FeCrO6 Double Perovskite Nanostructures: Multiferroic at Room Temperature

Arbitrary patterns of heteroepitaxial multiferroic Bi2FeCrO6 nanostructures are fabricated by pulsed laser deposition using a simple nanostencil approach. The crystal orientation and the shape of the epitaxial nanostructures are controlled by the orientation of the niobium-doped SrTiO3 substrates. Using advanced characterization techniques, it is established that the material retains its ferroelectric and magnetic properties at room temperature even at submicrometer dimensions.
