Abstract
We report x-ray-diffraction measurements of the microstructural origin of circumferential magnetic anisotropy [or orientation ratio (OR), the ratio of the remanent magnetization along the circumferential and radial directions] in textured magnetic recording disks. We study a series of CoPtCrB magnetic media with CrX underlayers with varying OR and quantify the anisotropic strain in the CrX underlayer and the c-axis alignment in the hexagonal-close-packed media. Our data show that the c-axis alignment results from the anisotropic strain in the underlayer and suggest that the OR comes predominately from the media c-axis alignment.
