Enhancement of transverse magneto-optical Kerr effects and high sensing performance in a trilayer structure with nanopore arrays

The transverse magneto-optical Kerr effects (T-MOKEs) and sensing performance in a magneto-optical surface plasmon resonance (MOSPR) structure comprising a nanoporous gold/Co6Ag94 bilayer with a square-subwavelength period on a gold slab are theoretically investigated. Benefiting from the excitation...
