The articles collected in this book cover a wide range of materials with extraordinary superconducting and magnetic properties. For many of the materials studied, strong electronic correlations provide a link between these two phenomena which were long thought to be highly antagonistic. The book reports both the progress in our understanding of fundamental physical processes and the advances made towards the development of devices.
