Evolution of magnetic properties with nanoparticle size. (a) Illustration of spin canting, the disorganization of spin close to the surface due to a lack of crystallinity organization. (b) Transmission electronic microscopy images of various IONPs synthesized through the thermal decomposition of Fe(acetylacetonate)3 in benzyl ether. (c) Size-dependent T2-weighted MR images of IONPs in aqueous solution at 1.5 T. Adapted from Ref. 9 (© 2005 ACS).
