Magnetic moments of iron clusters: A simple theoretical model Article uri icon

abstract

  • We present a simple model for the study of ferromagnetic transition metal clusters. Based on Fridel%27s model and on the geometrical characteristics, we obtain analytical expressions for the cluster average magnetic moment (μ̄N) as a function of the number of atoms in bcc structures. The oscillatory behavior of μ̄N as a function of cluster size reported experimentally in Fe clusters is reproduced by considering spherical bcc clusters. We briefly comment on the influence of ellipsoidal shape clusters on the magnetic moment measurements. © 1998 Elsevier Science B.V.
