Abstract

Ferrofluid offers useful applications with its tunable properties with external magnetic field. Dynamical response of the fluid to a stimulus, may depend upon the frequency of the stimulus. Here, we present our investigations of a ferrofluid using THz radiation. Commercial ferrofluid APG 2134 was investigated using THz-Time Domain Spectroscopy (THz-TDS), both, with and without the presence of externally applied magnetic field. The transmitted THz pulse shows a distinct change in its amplitude and pulse delay in presence of external magnetic field as compared with that in the absence of magnetic field. Due to the magnetic field induced ordered self-assembly structures inside the ferrofluid acting as a waveguide likely cause the changes in refractive index in THz regime. The observed results are useful for developing ferrofluid coupled THz structures capable of magnetically tuning their response.
