Paper Abstract

Optical head with magnetized garnet layer and noble metal grating is modeled. Incident P-polarized light affected by garnet layer changes its polarization due to Faraday effect. We can detect presence or absence of magnetic information after studying changes in polarization of the reflected light. Enhancement of the effect with plasmon resonance is shown.
