Investigation of magnetic fluids exhibiting field-induced increasing loss peaks

A theoretical analysis to explain an increase of the Brownian loss peak with increasing polarizing field, H, in a magnetic fluid, is presented. The model is based on the competition between the Brownian and Néel relaxation processes. It is demonstrated that in magnetic fluids with particles having s...
