Magneto-plasmonics on [CoPt/Ag] perpendicular magnetic stacked films was investigated for chemical sensing applications. Large magneto-optical enhancement was obtained under a surface plasmon resonance condition. Moreover, a magneto-plasmonic system with a Pd surface layer indicated distinct magneto-optical responses for a hydrogen gas exposure.
