摘要：

We report direct visual evidence for the association of particles in stable magnetic fluids in zero magnetic field, observed with cryo-transmission electron microscopy. The rather isotropic shape of the reversible associates indicates that isotropic (van der Waals) attraction is at least partly responsible for the particle association. (C) 1999 Elsevier Science B.V.
