The observation of an electric quadrupole interaction on dilute impurities of¹⁹²Ir in nickel using nuclear magnetic resonance on oriented nuclei

Abstract

The technique of near magnetic resonance on oriented nuclei (NMR/ON) has been used to identify a small electric quadrupole interaction on 192Ir nuclei, present as a very dilute in nickel: P=+0.30(05) MHz. This is interpreted in terms of an unquenched orbital moment at the impurity site.
