Magnetic molecules are at the very bottom of the possible size of nanomagnets and they provide a unique opportunity to observe the coexistence of classical and quantum properties.The discovery in the early 90's that a cluster comprising twelve manganese ions shows hyteresis of molecular origin, and later proved evidence of quantum effects, opened a new research area which is still flourishing through the collaboration of chemists and physicists. This book is the firstattempt to cover in detail the new area of molecular nanomagnetism, for which no other book is available. In fact, research and review articles and book chapters are the only tools available for new comers and the experts in the field. It is written by the chemists originators and by a theoristwho has been one of the protagonists of the development of the field, and is explicitly addressed to an audience of chemists and physicists, aiming to use a language suitable for the two communities. Zusammenfassung Focuses on molecular nanomagnetism, a research area which is of interest to chemists and physicists who want to discover the beauty of the molecular world and its potentialities to give various classes of magnetic materials.
