Abstract

The use of depth-controlled βnuclear magnetic resonance (NMR) to probe the magnetic properties of thin films and interfaces on a nanometer length scale was analyzed. It was shown that the a 30 keV beam of highly spin-polarized ⁸Li⁺ ions was slowed down and implanted into a 50 nm film of Ag deposited on a SrTiO₃ substrate. Two well resolved resonances which are attributed to Li occupying substitutional and octahedral interstitial sites in the Ag lattice were observed using a high field β-NMR spectrometer. The results show that the temperature dependence of the Knight shifts and spin relaxation rates are consistent with the Korringa law for a simple metal.
