The Magnetic Properties of Textured Fine Particle Systems

Abstract

The magnetic properties of fine particle systems are strongly dependent on two types of texture. The first is an orientational texture characteristic of the angular dispersion of the easy anisotropy axes and the second is a spatial texture characteristic of the physical microstructure of the system. The effects of texture on the properties of both fluid and solid dispersions of fine particles can be very pronounced. The paper reviews some recent studies illustrating these effects, with particular emphasis on the behaviour of recording media and magnetic fluids.
