Anomalous Decay in Short Time Response of Ternary Mixtures with Ferrofluid

We study the optical transmittance of ternary mixtures of water, glycerin and ferrofluids. These mixtures are subject to pulsed magnetic field and placed between crossed polarizers. After the magnetic field is switched off, the decay process is compared with q -exponential, stretched exponential, Mi...

Summary:We study the optical transmittance of ternary mixtures of water, glycerin and ferrofluids. These mixtures are subject to pulsed magnetic field and placed between crossed polarizers. After the magnetic field is switched off, the decay process is compared with q -exponential, stretched exponential, Mittag–Leffler, and one-sided Lévy stable functions. For short time, the experimental results are interpreted in terms of stretched exponentials. The parameters of this non-exponential relaxation are investigated as functions of temperature and the water, glycerin and ferrofluid concentrations.
