Abstract

Magnetite nanoparticles have been prepared by chemical co-precipitation method. The transmission of light through magnetic fluid has been investigated as a function of particles and thickness of the films with wavelength in between 450 and 750 nm, and parallel as well as perpendicular applied magnetic fields. It was found that the transmittance increased with the increasing applied magnetic field for both parallel and perpendicular directions. The onset of transmittance shifts to higher wavelength with increasing film thickness. For a given film thickness, the transmittance increases with increasing magnetic field. The ordered structures of the magnetic columns were formed in the magnetic fluid films under the influence of the external magnetic field are responsible for significant field dependent transmittance observed. We believe synthetized magnetic nanomaterial has a potential for magneto optic devices as well as biomedical applications.
