Show affiliationsPhysical parameters such as dielectric constant and susceptibility of dilute Fe3O4 ferrofluids derived directly from attenuated total reflection (ATR) and ferromagnetic resonance, respectively, were exploited to delineate the corresponding Faraday rotation angles with respect to applied magnetic fields. Theoretical estimation was compared with experimental measurements ensuring that the effective medium theory is admittedly correct and ATR is a prominent method to study the magneto-optical effect of ferrofluids.
