- W805119981 abstract "[ <TEX>$Co_{73}Pt_{27}-TiO_2$</TEX> ] 수직자기 기록매체에 대해 집속이온빔(FIB)을 이용한 <TEX>$Ga^+$</TEX> 이온 조사에 따른 자기적 특성의 변화를 조사하였다. <TEX>$Ga^+$</TEX> 이온 도즈량을 <TEX>$1times10^{15}ions/cm^2$</TEX>에서 <TEX>$30times10^{15}ions/cm^2$</TEX>까지 증가시켰을 때 도즈량 <TEX>$20times10^{15}ions/cm^2$</TEX> 이상에서 수직자기이방성 및 강자성 특성이 사라지는 것이 관찰되었으며, 이는 스퍼터링 효과에 따른 수직자기 기록층의 두께 감소보다는 <TEX>$Ga^+$</TEX> 이온 주입에 따른 수직자기 기록매체내의 조성 분포의 변화에 따른 것으로 보인다. <TEX>$Ga^+$</TEX> 이온 조사법을 이용하며 <TEX>$70times70nm^2,;100times100nm^2$</TEX> 크기의 자기구조체 패턴을 형성하였다. The effects of <TEX>$Ga^+$</TEX> ion irradiation on the magnetic properties of the <TEX>$Co_{73}Pt_{27}-TiO_2$</TEX> perpendicular magnetic recording media were investigated. As <TEX>$Ga^+$</TEX> ion dose increased from <TEX>$1times10^{15}ions/cm^2;to;30times10^{15}ions/cm^2$</TEX>, the perpendicular magnetic anisotropy was degraded and no longer observed above <TEX>$20times10^{15}ions/cm^2$</TEX> dose. The deterioration of the perpendicular magnetic anisotropy and ferromagnetic properties can be attributed to the concentration profile change due to Ga+ ion implantation. The magnetic islands of <TEX>$70times70nm^2;and;100times100nm^2$</TEX> size were successfully fabricated with <TEX>$Ga^+$</TEX> ion irradiation." @default.
