“…Kay et al proposed a model by Monte Carlo algorithm, where the columns consisting of magnetic particles were separated from each other. 4 Another model of Middleton et al, which was used for a study of the arctangent theory, assumed a column consisting of five segments of magnetic metals. 5 However, since the crystallites and columns in concern are quite tiny, e.g., around 10 nm, details on the microstructure, such as the shape, spatial distribution, and orientation etc., seem to be still unclear despite the foregoing works based on conventional electron microscopy.…”

Phys. 97, 073502 (2005); 10.1063/1.1866482Micromagnetic study of side-writing phenomena using thin-film heads and Co-CoO metal-evaporated tape 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 less dense.
