Abstract

A simple process to prepare monodisperse ferrimagnetic cobalt-substituted magnetite Co_xFe_3-xO₄ nanoparticles is reported. These ferrimagnetic nanoparticles are readily dispersed in hexane, forming a stable ferrimagnetic nanoparticle dispersion, and allowing easy nanoparticle self-assembly. When assembled under an external magnetic field (5.5 kOe), these nanoparticles show preferred magnetic alignment with their H_c reaching 2.49 kOe.
