摘要
Nanocrystalline Co/N thin him containing CO4 N phase has been deposited on Si (1 1 1) substrate by direct current magnetron sputtering in 10% N-2/N-2 + Ar discharge. The composition, structure and magnetic properties were examined by X-ray photoelectron spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM) and Superconducting quantum interference device. XRD and TEM investigations showed that the grain size of nanocrystalline Co-4 N was in the range 10-25 nm (with the error of +/- 0.2 nm). Magnetic analysis indicated that the synthesized Co/N thin films had good in-plane anisotropy. The value of H, with the domination orientation (1 1 1) was about 97 Oe. The saturation magnetization was estimated to be 103.9 +/- 6.1 emu/g, which was larger than the value of 46.5 emu/g firstly reported by Oda et al. (C) 2008 Elsevier B.V. All rights reserved.
