Visualisation of particle association in magnetic fluids in zero-field
Journal of Magnetism and Magnetic Materials
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
