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. info:eu-repo/grantAgreement/ES/DGA/E44-17R info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.097 2021 PHYSICS, CONDENSED MATTER 35 / 69 = 0.507 2021 Q3 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 206 / 344 = 0.599 2021 Q3 T2 0.606 2021 Electronic, Optical and Magnetic Materials 2021 Q2 Condensed Matter Physics 2021 Q2 5.5 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín, J.C.
