30 Apr 2008 | | Abstract: | Thin films of Co/Ru(0001) are known to exhibit an unusual spin reorientation
transition (SRT) coupled to the completion of Co atomic layers for Co
thicknesses under 4 layers. By means of spin-polarized low-energy electron
microscopy, we follow in real space the magnetization orientation during the
growth of atomically thick capping layers on Co/Ru(0001). Capping with
coinage-metal (Cu, Ag, Au) elements modifies the SRT depending on the Co and
overlayer thickness and on the overlayer material, resulting in an expanded
range of structures with high perpendicular magnetic anisotropy. The origin of
the SRT is understood through ab-initio calculations of the layer-resolved
contributions to the magnetic anisotropy energy. Besides the changes in the SRT
introduced by the capping, a quantitative enhancement of the magnetic
anisotropy is identified. The detailed analysis of the interplay between strain
and purely electronic effects allows us to identify the conditions that lead to
a high perpendicular magnetic anisotropy in thin hcp Co films. | | Source: | arXiv, 0804.4777 | | Services: | Forum | Review | PDF | Favorites | |
