Abstract
With better than 1% control of alloy composition, binary alloy films CoxNi1−x/Cu(100) with x⩽10% were prepared for the study of the spin-reorientation transition at variations of composition, thickness, and temperature. Only the films with a Co concentration less than 10% reveal the spin-reorientation with the film thickness. The critical thickness for the spin-reorientation transition was shifted drastically from 7.5 to 17.5 monolayers for a Co concentration variation from 0% to 8%. These findings indicate a strong influence of the composition on the magnetoelastic anisotropy. A kind of temperature-driven spin-reorientation from in-plane to perpendicular with increasing temperature was also found.
