Abstract

Polyelectrolyte-stabilised cobalt ferrite magnetic fluids demonstrate high relaxivity values at low fields. The magnetic suspensions are composed of compact metal oxide nanocomposites arranged in micelle-like structures which demonstrate an inverse correlation between relaxivity and hydrodynamic diameter (see graph). They can be aligned into linear arrays using an external magnet.
