Abstract

Large range well ordered epitaxial ferrimagnetic nominally Fe ₃O ₄ structures were fabricated by pulsed-laser deposition and embedded in ferroelectric PbZr _xTi _1-xO ₃ (x 0.2, 0.52) epitaxial films. Magnetite dots were investigated by magnetic force microscopy and exhibited magnetic domain contrast at room temperature (RT). Embedding ferroelectric PbZr _xTi _1-xO ₃ layers exhibit remnant polarization values close to the values of single epitaxial layers. Transmission electron microscopy demonstrated the epitaxial growth of the composites and the formation of the ferrimagnetic and ferroelectric phases. Physical and structural properties of these composites recommend them for investigations of stress mediated magneto-electric coupling at room temperature.
