Epitaxial patterned Bi2FeCrO6 nanoisland arrays with room temperature multiferroic properties

Abstract

Epitaxial multiferroic Bi₂FeCrO₆ nanoisland arrays with a lateral size of ∼100 nm have been successfully fabricated by patterned SiO₂ template-assisted pulsed laser deposition. The as-grown island structure exhibits promising multiferroic properties (i.e. ferroelectric and magnetic) even at nanometer dimensions at room temperature. This work demonstrates an effective strategy to fabricate high-density nonvolatile ferroelectric/multiferroic memory devices.
