Abstract

Dynamic nuclear polarization is a well-established technique, which has been used to produce polarized targets for experiments in nuclear physics, for example by Abragam & Goldman. This paper suggests experiments of a similar type, but involving the nuclear magnetic resonance of two isotopes (one stable, the other radioactive) in an antiferromagnet, ytterbium vanadate. At temperatures well below the Neel point 95 (2) mK, where linewidths should be comparatively small, the effects of cross-relaxation may be detected through changes in the rate of gamma-ray emission in a nuclear orientation experiment.
