Effects of Magnetic Fluid Concentration and Cell Size on Magneto-Optical Light Transmission

Abstract

In this study, magnetic liquids were first synthesized using the "high temperature hydrolysis reaction" method, which is a novel method for synthesizing magnetic field sensitive colloidal nanoparticles. For magneto-optical characterization, the magnetic liquids were exposed to magnetic field (0-600 G) in DC regime. The effects of concentration, cell size and magnetic field strength on light transmittance were observed. The largest change in light transmission was 10.4% for the sample with a concentration of 74%, 8.4% for the sample with 71% and 7.4% for the liquid with 66%. As the concentration increased, the power change increased and it was found that light transmission was high at low concentrations. As the cell size increased, the power variation was found to increase accordingly. This was explained in terms of the number of particles per unit volume and early saturation. Magneto-optical characterization studies have shown that these liquids can be used in various devices such as gaussmeter design in the optical field. This study revealed that the behavior of magnetic liquids changes in the presence of a magnetic field and that this behavior is affected by various conditions. The results show that the effect of magnetic fields on magnetic liquids is affected by a wide range of parameters.
