(Upper panel) Reconstructed phase image of the cross-sectioned Co-CoO evaporated tape that was subjected to recording bit length of 250 nm. (Lower panel) Simulated reconstructed phase image for the cross-sectioned Co-CoO evaporated tape that was subjected to recording bit length of 250 nm. The phase information is given in terms of φ.
Right
Changes in the reconstructed phase image with the application of magnetic fields perpendicular to the growth direction of the columnar structure. The phase information is given in terms of cos φ.
