Abstract

The behavior of the metallic multilayers of Si/\[Fe(10 nm)/Nb(4 nm)/Fe(4 nm)/ Nb(4 nm)\]2/\[Fe(4 nm)/Nb(4 nm)\]4 under 2 MeV Xeion irradiation has been investigated by depth profile analysis of Auger electron spectroscopy， Xray diffraction and vibrating sample magnetometer. The obtained experimental results show that the intermixing between Fe and Nb layers occurs in the 1.0×1014 ions/cm2 irradiated multilayer sample which results in the formation of Nbbased and Febased FeNb solid solution. For the samples irradiated to fluence larger than 1.0×1014 ions/cm2， amorphisation is observed， and moreover， the layered structure of the multilayer samples is broken up completely for the samples under 1.0×1016 or 2.0×1016 ions/cm2 irradiation. Vibrating sample magnetometer measurement also reveals that the magnetization of the samples changes with the evolution of the structure of multilayers. Possible mechanism of the modification in Fe/Nb multilayers induced by Xeion irradiation is briefly discussed.
