Effect of hydrogen plasma implantation on the micro-structure and magnetic properties of hcp-Co₈₀⁵⁷Fe₄Ir₁₆ thin films

【摘要】 We present detailed investigations of structural and static/dynamic magnetic properties of hydrogenated hcpCo₈₀⁵⁷Fe₄Ir₁₆ soft magnetic thin films. Two different kinds of defects, i.e., destructive and non-destructive, were demonstrated by controlling the negative bias voltage of the hydrogenation process. Our results show that the structure and magnetic properties of our sample can be tuned by the density of the induced defects. These results provide better understanding of the hydrogenation effect and thus can be used in the future for materials processing to meet the requirements of different devices.更多还原
