Evolution of orientation distribution of Co(110) crystal planes was determined by x-ray rocking curves. It has been found that: (i) The full-width at half maximum W of the Co(110) rocking curve decreases with both increasing Cr underlayer thickness dcr, and increasing CoCrTa magnetic layer thickness dco, especially in the thin layer regime. (ii) For the thin dcoregime, the interlayer diffusion between the Cr underlayer and the magnetic layer affects the rocking curves and magnetic properties significantly. (iii) Film magnetic properties, e.g., a significant jump in coercivity with increasing magnetic layer thickness in the thin dco regime may be related in part to the evolution of the Co(110) orientation distribution.
