Abstract
In this paper we report on an initial study of the magnetic properties of gamma-Fe2O3 and CrO2 dispersions as determined by pulse field magn etometry. Comparison with VSM measurements, in which the magnetic fiel d is applied for several seconds, shows that the adverse effects of th e magnetic field on the dispersion microstructure may, to a large exte nt, be mitigated by the use of pulsed fields. Remanence curves are use d to determine switching field distributions and to determine the qual ity of the dispersion.
