On the observability of NO NMR on a paramagnetic impurity in a diamagnetic metal

Abstract

The authors show that the observation of nuclear magnetic resonance detected by nuclear orientation technique (NO NMR) should be rather difficult for a radioactive nucleus belonging to a paramagnetic impurity in a metal. This arises both from the broadening of the NMR lines through electronic relaxation and also, when the electronic relaxation is slow, from the splitting of the resonance line due to the second order effects of the off diagonal elements of the hyperfine interaction.
