Finite spin chains made of few magnetic ions are the ultimate-size structures that can be engineered to perform spin manipulations for quantum information devices. Their spin structure is expected to show finite size effects and its knowledge is of great importance both for fundamental physics and applications. Until now a direct and quantitative(More)
Entanglement is a crucial resource for quantum information processing and its detection and quantification is of paramount importance in many areas of current research. Weakly coupled molecular nanomagnets provide an ideal test bed for investigating entanglement between complex spin systems. However, entanglement in these systems has only been(More)

Molecular-based nanomagnets form a class of materials where quantum effects can be observed on a macroscopic scale. Recently they attract much attention because of envisaged applications in the domain of magnetic storage, molecular spintronics and quantum computing. The success of such applications depends to the large extend on the precise modeling of(More)
