Abstract

Hybrid nanocomposites based on ferrimagnetic (FiM) Fe₃O₄ and magnetoelectric antiferromagnetic (AFM) Cr₂O₃ nanocrystals were synthesized to offer a particular three-dimensional (3D) interface between the two oxides. This interface favours an intermixing process (demonstrated by combining Raman spectroscopy and magnetization measurements) that determines the final magnetic behavior.
