摘要：

Atomic force microscopy (AFM), transmission electron microscopy (TEM), and ferromagnetic resonance (FMR) were used to unfold the nanoparticle size of a ferrofluid sample. Compared to TEM, the AFM method showed a nanoparticle diameter (D-m) reduction of 20% and standard deviation (sigma) increase of 15%. The differences in D-m and sigma were associated with the AFM tip and the nanoparticle concentration on the substrate. (C) 2001 Elsevier Science B.V. All rights reserved.
