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 . In this view it is not surprising that the magnetic properties of molecular clusters have a marked quantum character. On the other side the

Magnetism of Free and Supported Metal Clusters,sses involved when the free clusters cross a magnetic field. 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

Magnetism in Free Clusters and in Mn12O12-Acetate Nanomagnets, . These include atomic clusters containing ten to several thousand atoms, nanoscale materials, mono- and multi-layers, clusters deposited on surfaces, and the nanocrystal superlattices. The atomic arrangements and the physical, chemical, electronic, and the magnetic properties of these new mater

Delayed Ionization,gnitude of Planck’s constant. We also discuss newer work that identifies more prompt ionization channels, channels that are equally not direct. The existence of several time scales for ionization is discussed both quantum mechanically and statistically. Experimental results for fullerenes are presen

Future Directions,tum phenomenon can modify the behavior at reduced sizes and scale. There are however, outstanding problems that still remain unsolved. 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

Quantum and Classical Size Effects in Thermodynamic Properties,vior of small systems differ from their familiar counterparts for bulk matter. The greater part of the discussion focuses on phase changes and the properties of systems either in phase equilibrium or undergoing phase changes.
