Amorphous iron nanoparticles obtained by the sonication of Fe(CO) 5 in decalin were coated by various surfactants using the self-assembled monolayer (SAM) technique. They have been shown previously to behave as superparamagnetic materials. These meas

We demonstrate that the average size of the coated ferromagnetic Fe2O3 nanoparticles is controlled by the surfactant concentration in the coating solution. Magnetization as a function of this ratio first increases and then decreases exhibiting a peak
