概要
- 論文の詳細を見る
Thin films of the full-Heusler compound, Co2MnAl, were grown on Cr-buffered MgO(001) substrates at different growth temperature and post-annealing temperature by magnetron sputtering. Atomic force microscopy (AFM) and X-ray diffraction (XRD) measurements show that Cr-buffer layer can largely improve the surface morphology and structural quality of Co2MnAl film. The (001)-oriented epitaxial growth and B2 structure were confirmed by XRD measurements for all prepared samples. The smallest surface roughness ($\sim 2$ Å) and an identical $M_{\text{s}}$ value to the bulk value were obtained in the sample which was deposited at ambient temperature and post-annealed at 300°C.
