| Interface roughness effects on the giant magnetoresistance in magnetic multilayers are analysed theoretically for structures with non-conformal correlated interfaces. The roughness of each interface is described in terms of the K-correlation model and is characterized by the roughness exponent H(0≤H<1), correlation length ξ, and rms roughness amplitude Δ. Coherent scattering by different interfaces is also taken into account. |
