Abstract

Artificial modulation of magnetic structure on a monatomic layer scale has been examined in Co/Ru superlattices. The samples alternating Co 1 ML and Ru x ML (x = 1-4, ML: Monatomic Layer thickness) were prepared. Sharp fundamental and satellite peaks corresponding to superlattice structures are seen in the x-ray diffraction profiles for all the samples. For x = 1, furthermore, high-resolution transmission electron microscopy observation indicates the formation of an ordered structure with hexagonal-close-packed stacking of alternate Co and Ru atomic planes. The magnetization measurements show that only 1 ML difference in the Ru thickness has significant influence on the magnetic structure. The results are consistent with the first-principles calculations.
