Abstract
The effective viscosity has been calculated for a ferroliquid consisting of particles of cubic symmetry; the calculation is for strong magnetic fields much greater than the internal anisotropy field. The distribution of the orientation of the cubic axes is described by a Fokker-Planck equation, and this is used to calculate the antisymmetric part of the viscous stress tensor. The equation is solved by expansion in the small parameters τω and kaV/kT, where T is the Brownian rotational diffusion time and ω is the angular velocity of rotation of the liquid, while Ka is the magnetic anisotropy constant. An expression is derived for the effective viscosity. It is shown that the magnetoviscous effect for a nickel suspension is weaker than that for a suspension containing iron.
