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.
