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. Both the progress in our understanding of fundamental physical processes and the advances made towards the development of devices are reported here. The materials studied come in a variety of forms and shapes from bulk to epitaxial films, nano- and heterostructures down to those involving single molecules and double quantum dots. In some cases the structuring serves the study of bulk properties. More often it is the change of these properties with nanostructuring and the properties of different materials in close proximity with each other that are of key interest because of possible application of these materials or heterostructures to quantum computing and spintronics.
