Abstract
We present a model to describe a dynamic orientational response of a d ilute suspension of single-domain magnetic particles in a viscoelastic liquid carrier of the Maxwell fluid type. Introducing Brownian orient ational diffusion into the equation of the particle rotary motion, abs orption spectra of the initial dynamic magnetic susceptibility are obt ained. Under appropriate conditions they display a complex comblike st ructure which might be helpful for probing the local rheology of the c arrier medium of a suspension.
