Time integral and time differential measurements of the perturbed angular distribution of γ-ray transitions following the decays of the 3.83 MeV state in41Ca and the 1.29 MeV state in41K have been performed; the nuclei have been recoil implanted into magnetized iron foils after heavy ion reactions. A consistent description of the present and previous PAD and channeling data is obtained. In the system CaFe, the magnetic hyperfine field follows the bulk magnetization. In the system KFe, three fractions associated with different hyperfine fields are proposed which also account for the annealing behaviour and rapid loss of alignment observed.
