We report on the Kerr signal enhancement as a result of the capping effect of SnO2 on the CoFeSiB amorphous
layer. The magnetic layer was deposited by pulsed laser deposition method on Cu buffer layer and
was capped by SnO2 with different thicknesses. The magnetic behavior of the samples was investigated
by the Kerr effect. As the SnO2 thickness increased up to about 70 nm, the Kerr signal increased and then
reduced. The results were analyzed using the formalism based on the matrix method.
