用透射电子显微镜、X射线能谱仪和能量滤波器研究了Co-CoO斜蒸磁带的显微结构。观察到富钴区的柱状结构跨越整个膜厚。柱的直径从膜底部的20 nm增加到膜顶部的40 nm。在一个列内，观察到几个链的Co微晶躺在沿着列轴。构成链的单个Co微晶的直径在5和10 nm之间。在柱子的下部，几根链条组装成一束。在上部，Co链在柱的扩大直径中被CoO微晶分离。Co微晶的典型直径在膜的上部比在下部观察到的小。CoO微晶被发现是密集堆积在富钴柱之间，而以前的研究解释了钴柱之间的区域是无效的或…
Microstructure of a Co–CoO obliquely evaporated tape for magnetic recording was studied by transmission electron microscopy with an energy-dispersive x-ray spectrometer and an energy filter. Columnar structure of Co-rich region spanning through the film thickness was observed. The diameters of the columns increased from 20 nm at the bottom to 40 nm at the top of the film. Within a column, several chains of Co crystallites lying along the column axis were observed. Individual Co crystallite constituting a chain had a diameter between 5 and 10 nm. In the lower part of the column, several chains assembled to form a bundle. In the upper part, the Co chains were separated by CoO crystallites in the enlarged diameter of the column. A typical diameter of a Co crystallite was smaller in the upper part of the film than that observed in the lower part. CoO crystallites were found to be densely packed between Co-rich columns whereas previous studies had interpreted the regions between the Co columns to be voided or ...
