Magnetism of free and deposited magnetic molecules
Prof. Jürgen Schnack (Faculty of Physics, Bielefeld University, Germany)


Magnetic molecules constitute small quantum spin systems with interesting properties. After introducing this class of materials I would like to focus on the magnetocaloric properties of such molecules as well as on possible modification of magnetic properties in contact with non-magnetic metallic substrates. For each of these examples I am going to explain very recent theory developments to calculate magnetic observables for large spin systems.
