Abstract

The magneto-optical and optical properties of ultrathin Fe films sandwiched between Au layers were studied. A pronounced Kerr rotation peak is observed respectively in the photon energy range of 3.6-3.8 eV when the Fe layer is thinner than 1.5 nm, and in the range of 3.4-3.5 eV for thicker Fe layers. In simple calculations, the Kerr rotation peak is demonstrated to originate from the variation of the off-diagonal element in dielectric tensor of the Fe layers. The relative peak height Δθ_k, the normalized Kerr rotation θ_kn, and the effective optical constants at the photon energy of 3.5 eV are found to oscillate as a function of d_Fe.
