| Description | Journal: Journal of Physics D: Applied Physics This paper reports on the use of the autocorrelation function of the magnetization decay of a ferrofluid to investigate the effects which the moment of inertia of single domain ferromagnetic particles have on the frequency dependent complex susceptibility, xi ( omega )= xi '( omega )-i chi "( omega ), of ferrofluids. The contribution of particle inertial effects, arising from rotational Brownian motion, to an apparent resonance, indicated by the real component, chi '( omega ), going negative at a frequency lower than that predicted by theory, is investigated. The Langevin treatment of Brownian motion is used to incorporate thermal agitation into the analysis. |
