Abstract

(CO1-xFex)Pt films were grown on a glass substrate by a rf sputtering and then annealed at 650-700°C in a high vacuum. All the as-sputtered (Co1-xFex)Pt films deposited below 400°C had a disordered structure and showed very low coercivities. With increasing the deposition temperature and Fe contents, the (111) texture was weakened in as-deposited (Co1-xFex)Pt ternary films. Vibrating sample magnetometer and x-ray diffraction data show that Co atoms in the L10 CoPt phase were substituted with Fe atoms. In-plane coercivities of these films decreased almost linearly with increasing Fe content which seemed to be due to the decrease of a crystalline anisotropy energy.
