ABSTRACT
We propose a simple model to estimate the effective moments of free clusters in a magnetic field. Compared with supported clusters, the effect of magnetic anisotropy is significantly enhanced, in good agreement with experimental results. The controversy of relations between the effective moment and cluster temperature presented in experiments is explained within our model. We can evaluate the magnetic anisotropy energies of free clusters from Stern-Gerlach experimental results.
