The temperature effects on the magnetic properties of transition metal
clusters are investigated by computer simulations which combine the
classical potential approximation with the generalization of our
recently proposed tight-binding molecular-dynamics method that
includes explicit incorporation of spin-orbit interactions and spin
fluctuations. The efficacy of this new method is demonstrated by
application to small and intermediate size Nin-clusters () for which experimental data are available for comparison. The
results obtained are in good agreement with the recent experimental
findings.
