Abstract

Two magnetic latex preparations have been measured by polarized and depolarized dynamic light scattering. The adherence of the latexes to a simple physical model, that of a bar magnet embedded in a plastic sphere, is judged adequate in one case, but not the other. Preliminary efforts to use the latex spheres as probes of sodium polystyrene sulfonate solutions are described. A few observations are made concerning the dynamic light scattering behavior of the magnetic latex under the influence of an externally applied, oscillating magnetic field.
