Abstract

In this paper, the effect of Au nanoparticles and a Bragg reflector mirror on the optical and longitudinal magneto-optical Kerr effect of a new magneto-plasmonic structure has been investigated. The new magneto-plasmonic heterostructure consists of a Bragg reflector mirror beside a crystalline Ce:YIG thin film incorporating gold nanoparticles. Our results indicate sufficient broad band longitudinal magneto-optical Kerr effect enhancement in this new structure using the combination of surface plasmon resonance and Bragg reflector mirror.
