Modulated adiabatic passage on oriented nuclei (MAPON) is a technique
developed specifically to measure very small electric quadrupole interactions
(EQIs) at radioactive probe nuclei even when such interactions are masked in
the frequency domain by inhomogeneous magnetic broadening associated with a
dominant magnetic hyperfine interaction. In this paper an overview of the
technique is presented with particular reference to
60CoCo EQI measurements which were
an important step in establishing MAPON methodology. MAPON results for dilute
nd impurities in ferromagnetic Fe and Ni metal hosts are reviewed including
presentation of new data for
58CoNi and
60CoNi. Priorities for future
studies are provided on the basis of this review.
