Synopsis:
Magnetic nano-objects can range from single atoms to large clusters or nanostructures, displaying a variety of physical effects and being under intensive investigation for applications in nanotechnology, from magnetic circuit elements for spintronics to qubits for quantum computing. The main goal of this lecture is to introduce the fundamental quantum-mechanical principles governing the physics of such magnetic nano-objects, combining simple theoretical models with recent experimental and computational advances, in order to give the student a broad understanding of this area of research.
