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.
