Abstract
Abstract: Ferromagnetic resonance (FMR) is used to probe the magnetic properties of Co/Ag superlattices (SLs) with ultrathin Co layers (2-6 angstrom). Different series of 5x[Ag/Co] multilayers have been grown by molecular beam epitaxy on Si(111) substrates, monitoring the growth by reflection high energy electron diffraction. Cross-section transmission electron microscopy confirms the growth of local areas with the designed SL periodicity, a sharp compositional modulation, well defined Ag-Co interfaces, and a perfect fcc (111) stacking. FMR spectra have been recorded at various polar angles in the 0 degrees-90 degrees range. A single and extremely broad resonance peak is observed in all cases. While SLs with Ag layers thinner than 10 angstrom exhibit similar values of the perpendicular anisotropy, a clear reduction is observed for samples with Ag layers about 14 angstrom thick. Possible causes for this change are discussed. (c) 2008 American Institute of Physics.
