High-frequency conductivity and magnetoreflection of light from magnetic multilayers

We consider the high-frequency conductivity of magnetic multilayers and show that for the high-frequency conductivity there is a giant magnetoresistance effect. The relative change of the high-frequency conductivity for frequencies ωτ ∼ 1 has equal imaginary and real parts, where τ is the relaxation...

Description
Summary:We consider the high-frequency conductivity of magnetic multilayers and show that for the high-frequency conductivity there is a giant magnetoresistance effect. The relative change of the high-frequency conductivity for frequencies ωτ ∼ 1 has equal imaginary and real parts, where τ is the relaxation time. It is shown that the relative change of the deviation of the reflectivity of magnetic multilayers in the magnetic field from 1 is large and that a magnetic multilayer is a dispersive magnetic mirror, which is controlled by the magnetic field and the relative change of the reflectivity of light is frequency dependent.
