Magneto-optical investigation of Au/Cu-wedge/NiFe sandwiches

The investigation of Cu-thickness dependence of magnetic and magneto-optical properties f Au/Cu-wedge/NiFe sandwiches were performed with help of the magneto-optical method with micron resolution. It was discovered that the magnitude of the transverse Kerr effect (TKE) oscillates, as Cu-wedge thickness is variable. It was found the period of these oscillations is equal to ∼ 6A. It was proved that TKE oscillations are caused by the influence of finite-size effect.
