Detecting Magneto-Optical Interactions in Nanostructures

Effects due to magneto-optical interactions are responsible for most of thephenomena discovered in optoelectronics and spintronics. Magneto-opticalinteractions can generate elementary excitations of the order of light-magneticmatter, which can flow under certain conditions. Here, we observe theintensities of magneto-optical interactions in hexagonal arrays of magneticnanowires using experimental measurements and simulations. Nanowires of threematerials (cobalt-Co, iron-Fe, and nickel-Ni) were electrodeposited on aluminamembranes by the AC electrodeposition method. Our results reveal that themagneto-optical behavior can produce, under certain conditions, a kind ofavalanche of magneto-optical interactions, which is dynamic. Such anobservation shows the possibility of generating a magneto-optical current(spin-opto current).
