Epitaxial patterned Bi 2 FeCrO 6 nanoisland arrays with room temperature multiferroic properties.

Epitaxial multiferroic Bi 2 FeCrO 6 nanoisland arrays with a lateral size of ∼100 nm have been successfully fabricated by patterned SiO 2 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.
