Abstract
In ferromagnetic Ni-, Co- and Fe-alloys of transition metals the formation and activation energies for reorientation of diatomic impurity-hydrogen-complexes have been studied by means of measurements of the magnetic after-effect. Diatomic complexes were found to be formed if the impurity atom had a smaller number of d-electrons than the atoms of the host lattice. The relaxation times for MeH- and MeD-complexes (Me denoting the metal) show significant isotope effects of the activation energies (Q D- Q H≃40–50 meV) and the pre-exponential factors (toh/ tod≃10).Keywords
