G705 Influence of the Spin Rotational Brownian Motion on the Negative Magneto-Rheological Effect in a Dispersion Composed of Rod-like Hematite Particles

Abstract

We have shown the basic equation of the orientational distribution function of prolate spheroidal hematite particles that conduct the rotational Brownian motion in a simple shear flow under an applied magnetic field. The equation has been solved numerically in order to investigate mainly the influence of the spin rotational Brownian motion on the orientational distribution, the negative magneto-rheological effect and the characteristics of magnetization.
