TEM images of Cu nanoparticles that were grown on TEM grids alongside samples prepared for XMCD measurements. The growth conditions, average particle sizes with standard deviations, and particle densities are given.
(Color online) (a) -edge XMCD spectra from the Cu nanoparticles, offset vertically for clarity. The inset shows a typical absorption spectrum. (b) -edge spectrum from Co with its absorption spectrum in the inset for a Cu thin film sandwiched between Co. The areas under the and peaks were used to obtain the moments listed in Table I.
(Color online) The spin moments for the thin films (●) as a function of film thickness . The line is a fit using dependent function. The moments from the nanoparticles (×) are shown as a function of their diameter.
Spin and orbital magnetic moments extracted from the XMCD spectra of nanoparticles and thin films. The average sizes, standard deviations, and densities of the nanoparticles are listed. The Co moments for the film serve as reference. Errors in the spin moments were estimated to be less than 10% based on the fits to the and peaks.
