Quantum Tunneling of the Magnetization in Molecular Nanoclusters,ers are small objects characterized by a small spin compared to single domain particles but significantly larger than the largest spin observable in atoms [1]. In this view it is not surprising that the magnetic properties of molecular clusters have a marked quantum character. On the other side the

For transition metal clusters of a few 10 to a few 100 atoms the observable projection of the magnetic moment onto the field axis (similar to magnetization) measured from the clusters deflection, scales with magnetic field, clusters size a

These include atomic clusters containing ten to several thousand atoms, nanoscale materials, mono- and multi-layers, clusters deposited on surfaces, and the nanocrystal superlattices.

In the area of thermal properties, the variation of the melting point, changes in entropy at the melting and the negative heat capacity are still not understood. In
