The structure and the electrical properties of a multilayer system based on a composite (Co40Fe40B20)34(SiO2) and zinc oxide

A heterogeneous multilayer system (Co 40 Fe 40 B 20 ) 34 (SiO 2 ) 66 /ZnO was obtained by ion-beam sputtering. X-ray diffraction analysis showed that the obtained films have an amorphous multilayer structure. Transmission electron microscopy analysis (TEM) confirmed the formation of separated (Co 40 Fe 40 B 20 ) 34 (SiO 2 ) 66 and ZnO layers. The (Co 40 Fe 40 B 20 ) 34 (SiO 2 ) 66 composite layers are monogranular with a metal particle size of 1 nm. The thin films remain stable after heat treatment at temperatures up to 350 °C. Measurement of the electrical resistance confirms the formation of a multilayer structure and crystallization of films after heating above 350 °C.
