Abstract

A series of FeCl/Cu multilayer thin films was deposited with different thicknesses of Cu layer. The multilayers were sputtered with a two dc magnetrons system. The effect of different thicknesses of Cu layer on the properties of the films was investigated. The Cu content in the films gradually increased from 0 at.% to 47 at.% as the Cu layer thickness was increased from 0 nm to 24 nm. According to crystal structure analysis, the intensities of the peaks which belong to the face centered cubic planes increased with increasing Cu content of the films. Modest and mirror-like surfaces were observed in all images obtained by a scanning electron microscope. Magnetic measurements indicated that magnetization decreased with increasing Cu contents in the multilayer thin films. The magnetization of the film without Cu was 1473 emu/cm3 while the value of 348 emu/cm3 was detected for the film with 24 nm Cu layer thickness..
