dc.description.abstract | 此研究係研製單層CoTbAg 薄膜以應用於近場光學寫入與磁通量讀取的記錄媒體。採用直流磁控濺鍍,在玻璃基板及表
面自然氧化之Si 基板上鍍製Co68.48-XTb30.52AgX 合金薄膜,其中X= 0~25 at.%;並以射頻磁控濺鍍在薄膜上下各濺鍍
一層SiNx 保護層,避免其氧化。探討非磁性元素Ag 之含量對Co68.48-XTb30.52AgX 薄膜之微結構及磁性質的影響。X-ray 繞射及TEM 電子繞射結果顯示所有的薄膜均為非晶質。其中Co67.23Tb30.52Ag2.25 薄膜在室溫的Ms 值約為310 emu/cm3, Hc⊥值為3100Oe,當溫度由室溫上升至200 °C 時,其Ms 及Hc⊥值急速下降。此薄膜之補償溫度Tcomp 約為225 °C,具有應用於近場光學寫入與磁通量讀取的記錄媒體之潛力。 | zh_tw |
dc.description.abstract | This work fabricates a single-layer
CoTbAg film for near-field optical write and
magnetic flux detection recording medium
application. Co68.48-XTb30.52AgX films with X=
0~25 at.% are deposited on glass and naturally
oxidized silicon wafer substrate by dc
magnetron sputtering. The magnetic film is
sandwiched between SiNx protective layers to
prevent oxidization. The effects of
non-magnetic element Ag content on the
magnetic properties and microstructure of the
film are investigated. X-ray diffraction and
transmission electron microscope diffraction
patterns revealed that all the films are
amorphous. The saturation magnetization of
the Co67.23Tb30.52Ag2.25 film is about 310
emu/cm3; perpendicular remanence is about
255 emu/cm3, and the perpendicular coercivity
is about 3100 Oe at room temperature. The
saturation magnetization and perpendicular
coercivity decrease rapidly as temperature
increases from room temperature to 200 °C.
The compensation temperature Tcomp of this
film is about 225 °C. This film is a promising
candidate for near-field optical write and
magnetic flux detection recording media
applications. | en |
