| Outline of Final Research Achievements |
Magneto-optical (MO) properties of perpendicular magnetic nanostructures were investigated for chemical and biological sensing applications under polar Kerr measurement conditions. Magnetic stacked films with a MO cavity effect indicated a giant Kerr rotation angle of approximately 20 degrees. The films were desirable in chemical sensing applications because the MO cavity was sensitive to the optical conditions of the film surface. The films with Pd surface layer displayed a distinct MO response to hydrogen gas at ambient temperature in real time. Moreover, the magnetic nanostructures with noble metal fine grains exhibited a polarization reversal on Kerr rotation. The Kerr loop of the nanostructures depended on the external environment also. These MO behaviors on the nanostructures are attributed to the influence of localized surface plasmon polaritons excited at the noble metal fine grains.
