Low-field magnetic susceptibility (real susceptibility at 1 Hz) of magnetite (S) with a positively charged bare surface and oleic acid coated magnetite (S) dispersed in 90 vol% solution of acrylic acid in water, normalized to their initial value χ_max at 1 Hz. Positively charged magnetite (S) shows an immediate decrease of magnetic susceptibility due to dissolution of the particles, whereas the decrease of the magnetic susceptibility of oleic acid coated nanoparticles is slowed down by ligand exchange.
