Abstract
The reflection of visible light (wavelength from 350 to 800 nm) on magnetic granular thin films Cox-Ag1-x with x from 0 to 35 at % was studied. Dependence of reflection (R) is strong on magnetic and percentage of Co in the thin films, R strongly increase in wavelengths 560 and 660 nm. In this paper, some arguments relating to the spin-plasmon phenomenon were used to explain the results. Key words: Granular magnetic thin films, visible light, reflection, spin-plasmon.
Highlights
The granular ferromagnetic thin films (example: Co-Ag; Co-Cu; Fe-Cu, etc.) has been studied through the phenomenon of giant magneto resistance (GMR)
The granular ferromagnetic thin films has been studied through the phenomenon of giant magneto resistance (GMR)
When magnetic field applied to the thin film0.5s with visible light has a smaller wavelength, reflection (R) is almost unchanged
