Magnetic Resonance of Au:Er167and Au:Yb171

Abstract

The hyperfine splitting of (enriched) Au: ${\mathrm{Er}}^{167}$ and Au: ${\mathrm{Yb}}^{171}$ dilute alloys is reported. The absence of the signal from the $I=0\mathrm{}$ isotopes enables a more accurate determination to be made of the hyperfine splitting parameter and of the temperature dependence of the linewidth than in a previous publication.
