摘要：
The results of theoretical and experimental studies of the effect of the perturbation of magnetization of magnetic fluid in the initial part of magnetization curve, caused by thermal oscillations in the adiabatic sound wave are considered. The measurements were carried out on the magnetic colloid samples with different viscosity of the dispersion medium within the frequency band of 20-60 kHz. In this frequency band, studied samples are characterized by the absence of thermal relaxation of the magnetization. The comparison of the conclusions of the model of thermal relaxation of magnetization and the experimental results makes it possible to obtain information about the features of the rheology for the nearest molecular environment of a particle - nanorheology.
