We present a simple model for the study of ferromagnetic transition metal clusters. Based on Fridel’s model and on the geometrical characteristics, we obtain analytical expressions for the cluster average magnetic moment (μ N ) as a function of the number of atoms in bcc-structures. The oscillatory behavior of μ N as a function of cluster size reported experimentally in Fe clusters is reproduced by considering spherical bcc-clusters.
