Title: Transverse Tunable Magneto-Plasmonic Kerr Effect in Large Area Micro-Patterned Au/Co/Au Structures

Abstract

By sputtering the sequence of Au/Co/Au layers on ordered microspheres, two-dimensional plasmonic arrays with sufficient angular tunability and enhanced transverse magneto-plasmonic Kerr effect are fabricated. For confirmation of enhanced optical properties, we simulated the fabricated sample using the finite difference time domain method. In order to investigate the effect of rotation speed on the anisotropy of the samples and their magneto-plasmonic responses, these patterned structures are fabricated under dissimilar holder rotation speeds for inner cobalt layer deposition (i.e., Au (10 rpm)/Co (30 rpm)/Au (10 rpm) and Au (10 rpm)/Co (10 rpm)/Au (10 rpm) structures). Our results show that the transverse magneto-plasmonic Kerr effect measurements can provide unique and useful information about the structure and quality of the fabricated samples. In addition, the ability of the samples as a tunable magnetic field sensor has been investigated.
