Abstract:

Dynamical response functions to an external magnetic field as well as rheological properties of moderately concentrated magnetic colloids have been calculated by methods of statistical physics. Hydrodynamic and magnetodipole interactions between the particles were taken into account. We suppose that ferroparticle magnetic moment is constant in its absolute value and is frozen into the particle body. Our analysis has shown that the magnetodipole interaction increases magnetic response functions and rheological parameters of the colloid as well as characteristic relaxation times of both colloid magnetization and hydrodynamic stress. We have studied some pecularities of hydrodynamical behaviour of the ferrocolloid in an oscillating magnetic field. (C) 1999 Elsevier Science B.V. All rights reserved.
