Directed Self-Assembly of Epitaxial CoFe2O4-BiFeO3 Multiferroic Nanocomposites

Abstract

CoFe${}_2$O${}_4$ (CFO)-BiFeO${}_3$ (BFO) nanocomposites are an intriguing option for future memory and logic technologies due to the magnetoelctric properties of the system. However, these nanocomposites form with CFO pillars randomly located within a BFO matrix, making implementation in devices difficult. To overcome this, we present a technique to produce patterned nanocomposites through self-assembly. CFO islands are patterned on Nb-doped SrTiO${}_3$ to direct the self-assembly of epitaxial CFO-BFO nanocomposites, producing square arrays of CFO pillars.
