Abstract

Modulated adiabatic passage on oriented nuclei has been used in combination with beta-ray detection to make a definitive measurement of a nuclear electric quadrupole hyperfine interaction in elemental iron. For ⁵⁹Fe in single-crystal iron magnetized along the easy (100) direction P/h=3eQV_ZZ/4I(2I-1)h = + 19.4(5) kHz, and along the hard (111) direction P/h = + 20.2(5) kHz. Theoretical estimates for the ⁵⁹Fe ground-state nuclear electric quadrupole moment are considered in terms of the particle-rotor model and the shell model. A value of Q = +0.19(3) b is adopted, which, in turn, is used to obtain electric field gradient values at the Fe site of V_ZZ = + 1.7(3) × 10¹⁹ V m^-2 and + 1.8(3) × 10¹⁹ Vm^-2 for magnetization along the easy and hard directions, respectively. Comparisons are made with previously measured results for the nearby 3d impurities Mn and Co in Fe.
