Spin - from classical magnetism to quantum spintronics technology
The Lecture Course, which is offered in the winter semester 2018-2019 in the module "Materials Science" can also be taken as "Ausgewählte Kapitel der Festkörperphysik".
If you are interested to be credited as "Ausgewählte Kapitel der Festkörperphysik", get in touch with M. Kläui (Klaeui@uni-mainz.de).
The lecture is based on the knowledge acquired during the bachelor's program with the content adjusted based on the prior knowledge of the participants. Time and place may be changed, if necessary, after consultation with the participants. The lecture course will be given in English to cater for students from all backgrounds.
Contents:
Spin is everywhere – from governing chemical reactions to data storage technology, medical imaging and future quantum technologies.
In this lecture, the physics of spins, ranging from the fundamentals of classical magnetism to magnetic and magnonic spin transport and device applications is covered. The lecture covers the basics up to current applications in microelectronics and medical technology including commercially available magnetic data storage and sensors as well as novel emerging concepts for new efficient and miniaturized devices based on quantum effects.
The lecture starts with an introduction to magnetism, collective phenomena, the domain structure, spin dynamics and micromagnetic models for spin structures on the nanoscale. More advanced topics are magnetoresistance effects and spin-dependent transport, which are used, for example, in magnetic storage, logic or for energy production from waste heat ("energy harvesting"). In addition to the physics of the effects, modern experimental techniques for measuring and imaging the discussed systems will also be presented.
Beyond the classical magnetism, artificial quantum spins such as spin dots and superconducting qubits are explained. The implementation of these solid state quantum circuits in quantum coherent devices ranging from quantum simulators, quantum sensing to quantum information processing covered within the course.
The lecture gives an introduction to the basics of the two areas and discusses current examples. Online material and exercises will be used to deepen the understanding. Depending on the interest of the participants, hands-on experiments, lab-tours and excursions to companies, e.g. producers of magnetic sensors, are offered.
