The magnetic anisotropy of terbium, holmium and thulium as dilute substituents in single crystals of ferromagnetic gadolinium has been studied by pulsed NMR measurements on 159Tb, 165Ho and 169Tm. Results are compared with calculations based on crystal-field parameters derived from torque magnetomery . Significant discrepanies are found and attributed to non-uniformity of the gadolinium magnetisation in the neighbourhood of the solute ions.
