Abstract
The influence of temperature on the ferrofluid magneto-optical response after magnetic field commutation is studied. Its contribution to the diffusion and mobility of the ferrofluid nanoparticles is considered by means of thermal agitation and the temperature-dependent viscosity of the fluid. Experimental responses after magnetic field switch on and off show a significant dependence on temperature. Taking into account both mentioned thermal influences, a qualitative description is provided, in which viscosity turns out to play an important role. In addition, a model based on an adaptation of a paramagnetic gas theory is used to analyze the transmission relaxation evolution after magnetic field switch off. The results are in good agreement with the experimental measurements, demonstrating the validity of this adaptation to consider the temperature dependence of this response.
