摘要
We report the magneto-optical Kerr signal enhancement due to the capping effect of SnO2 on the Co67Fe4B14.5Si14.5 amorphous ribbons. The amorphous melt spun ribbons are mounted on glass substrate and capped by SnO2 with different thicknesses by using electron-beam evaporation technique. The magnetic behavior of the ribbons is investigated by the magneto-optical Kerr effect. As the SnO2 layer thickness increases up to about 70 nm, the Kerr signal increases more than two times with respect to that for uncovered ribbon. The results were analyzed using a formalism based on a 4 x 4 matrix method. A good agreement of the experimental results with the theoretical results is observed.
