Magnetic non-magnetic transitions in non-magnetic transition metal clusters Article uri icon

abstract

  • The critical size for the magnetic non-magnetic transition in non-magnetic 3d and 4d metal clusters is studied by means of a tight-binding Friedel model and the Stoner criterion. The density of states is modeled by geometric shapes that include a dependence on the number of electrons. The second-moment approximation is used to introduce a cluster size-dependent band-width. We apply this model to estimate the critical sizes for the magnetic transition. © 1997 Acta Metallurgica Inc.
