Abstract

A low energy beam of spin polarized ⁸Li has been used to study the behaviour of isolated ⁸Li implanted into a 150 nm thick film of Al on an MgO substrate. The spin relaxation rate 1 / T₁ and β-NMR lineshape were measured as a function of temperature in a large magnetic field of 4.1 T. The resonances from different sites are unresolved due to the large nuclear dipolar interaction with the host ²⁷Al magnetic dipole moments. Nevertheless the temperature variation of the site averaged 1 / T₁ and Knight shift show evidence for a transition between the octahedral O and substitutional S sites at about 150 K, as observed in other fcc metals.
