In this work, Fe<sub>3</sub>O<sub>4</sub>-based nanomagnetic fluid was synthesized using a chemical co-precipitation method. The structural, morphological, and magnetic properties of the fluid were investigated using sophisticated characterization techniques including x-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and vibrating-sample magnetometry (VSM). Our investigation focused on the tunability of magneto-optical transmittance as a function of the varying magnetic field at different particle concentrations. Further, we observed variations in diffraction fringes in the nanomagnetic fluid, correlating with particle concentration, by passing a high-power laser through the diluted fluid system. Light–matter interaction in the presence of a varying magnetic field induces optical anisotropy in the fluid, whereas dipole–moment interaction and magnetic particle alignment in the presence of a magnetic field are the main supporting phenomenon of magneto-optical tunability in our experiment.

The polar molecule DMSO is known to enhance the electrical properties of PEDOT, with the underlying mechanism believed to involve structural changes in PEDOT that improve carrier mobility, although carrier concentration has a more pronounced effect on conductivity. In this study, we examined the impact of varying DMSO concentrations on PEDOT. With the optimal addition of DMSO (10 vol.%), PSS and PEDOT were effectively separated, resulting in parallel lamellar microstructures that improved the continuity of the conductive network. Hall effect measurements showed significant increases in both carrier concentration and mobility. The PEDOT<sup>+</sup> polaritons were arranged parallel to the lamellar structure, facilitating rapid charge transport along the molecular chains. This arrangement led to enhanced three-dimensional charge transfer, increased π-π conjugate stacking between microstructural layers, and a greater electron cloud density. The synergistic effect of these changes resulted in a three-fold increase in film conductivity. Additionally, lightly doping PEDOT with DMSO led to a 35% increase in the Seebeck coefficient with rising operating temperatures.
