Paper Abstract

Based on the optical and magneto-optical properties of single crystalline CoFe204, the enhancement of magneto-optical rotation in thin CoFe204 films has been studied. It will be shown both theoretically and experimentally that the rotation can be increased considerably by optimizing the thickness of the CoFe204 film in combination with auxillary non-magnetic thin films. F8r readout at AlGaAs laser wavelengths ( ~800 nm) this resulted in an overall rotation of 8o at 20% sample reflectance.
