Effect Magneto – Optic on Ferromagnetic Nanoparticle Polymer Composite Films
Zaid A. Hasan
Abstract
Optical properties of a composite material made of ferromagnetic matel nanoparticles embedded in dielectric host are
studied. A nonlinear dependence of the optical rotation on magnetic field resulting from the reorientation of
nanoparticles is demonstrated. The data of optical properties finding were applied to the magneto – optic
experimental data of nickel ferrite (NiFe2 O4) ferromagnetic nanoparticles embedded in polymer (PMMA) host. The
magneto – optic is applied at wavelength (540 nm) and magnetic field intensity (450 m T), from result we found the
affect magneto – optical on samples
