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 8^o at 20% sample reflectance.
