Abstract
The magnetic properties, the microstructures and the chemical binding state of carbon atoms of Fe-polyethylene films prepared by co-evaporating Fe and polyethylene were investigated. Magnetic property measurements revealed that the dependence of the saturation magnetization of Fe-polyethylene films on the carbon content was different from that of sputtered Fe–C films, and that Fe-polyethylene films with the carbon content of 11–13 at.% exhibited good soft magnetic properties. The magnetic properties of the Fe-polyethylene film with the carbon content of 11 at.% were as follows; Ms=1390 emu/cm3, Hc=2 Oe, µ=2000 (at 1 MHz), µ=900 (at 10 MHz). The temperature dependence of Ms and Hc indicated that the crystallization temperature was about 240–260°C. The results of XPS showed that most carbon atoms in the Fe-polyethylene films chemically combined with Fe atoms.
