Abstract

The growth mechanism that determines the microstructure of obliquely evaporated Co-CoO tapes has been investigated. A preferred orientation relation hcp-Co 〈001〉/CoO〈111〉 is found in the neighboring grains when the hcp-Co grains grow on top of the CoO. However, no preferred orientation is observed in the lower to middle part of the magnetic layer when the CoO grains grow on top of the hcp-Co. The structural properties of the Co-CoO tapes can be explained accordingly based on the preferred orientation relation.
