NUCLEAR RESONANCE OF A1 IN SYNTHETIC RUBY

Abstract

INITIAL STUDIES ON THE NUCLEAR MAGNETIC RESONANCE OF Al in ruby are summarized. LiCl containing Mn ion impurities was prepared. Nuclear resonance studies were performed on the Li at room temperature, liquid N and liquid He temperature. Electron paramagnetic resonance studies were performed at room temperature on the Mn ions. The Mn appeared to exist in the crystal in 2 phases, dilute and concentrated. In the dilute phase the Mn ion concentration in the host LiCl was 0.2 mole-%; in the concentrated phase the Mn ion concentration was 100%, indicating precipitation as a pure crystal. LiF with Mn ion impurity was also prepared. The microwave spectrum indicated that up to concentrations of 10 mole-% of Mn there is no tendency of the Mn ions to form 2 phases or to precipitate separately from the LiF; there was no measurable diffusion of ions at room temperature. Other experiments included a search for an electric hexadecapole moment in In and Sb.
