Investigation of CoFeV/TiZr Muitilayer by Polarized Neutron Reflectometry

Abstract

The interfacial structures of CoFeV/TiZr multilayer play an important role in performance of polarizing supermirrors.Aiming to requirement,CoFeV/ TiZr layered samples with different structures were prepared.Specular reflection of polarized neutrons was employed to study the depth profile of scattering length,density,thickness and roughness of CoFeV/TiZr multilayer and magnetically dead layers.The result shows that the roughness in CoFeV/ TiZr multilayer can be described with roughness increase law and the thickness of magnetically dead layers is about 0.5 nm.The producing technology of the multilayer reaches the requirements.
