Abstract

We presented the results of modeling the magneto-optical properties of nanoscale layered structures based on the permalloy-tantalum structure on a silicon substrate. The spectral dependences are calculated in the transverse geometry of the magneto-optical Kerr effect in the range of 0.5–4.0 eV, while a highly nonlinear behavior of the spectral dependences was established depending on the thickness of the permalloy and tantalum layer. It is also shown that the Kerr effect can be significantly enhanced with sufficiently large values of the thickness of the tantalum layer.
