MA 17: PhD Focus Session: The Hitchhiker’s Guide to Spin Phenomena at the Space and Time Limit

Dienstag, 6. September 2022, 15:00–17:00, H43

The growing hunger of society for fast data storage and processing, together with the end of Moore’s law, demand the development of new technologies to implement smaller, faster and more power-efficient devices. Research in magnetic materials has shown the potential of spin-based devices in this regard. Pushing for ’More than Moore’ devices, space and time limits need to be tackled. At the heart of this research are three fundamental operations: Control of magnetic order, spin transport and efficient monitoring of spin angular momentum in space and time. Topical clusters ranging from ferro- to antiferromagnets up to 2D materials, magnetic-organic interfaces and heterostructures are extensively studied. New materials and concepts are being developed rapidly which can appear very complex to someone new to the field. Young researchers often manage to get an overview of their own specific field but lack the big picture. For this reason, this PhD symposium will focus on talks in mostly tutorial-like style, yet will also include recent highlights. In addition, the symposium aims to exchange ideas and foster discussions on a broad range of spin phenomena. Organizers: Yannic Behovits (Physics, Freie Universität Berlin and Fritz Haber Institute of the MPS), Mona Bhukta (Physics, Johannes Gutenberg University Mainz), Bikash Das Mohapatra (Physik, Martin-Luther-Universität Halle-Wittenberg), Oliver Gueckstock (Physics, Freie Universität Berlin and Fritz Haber Institute of the MPS), Hendrik Meer (Physics, Johannes Gutenberg University Mainz), Maximilian Paleschke (Physik, Martin-Luther-Universität Halle-Wittenberg), Eva S. Walther (Physics, Technische Universität Kaiserslautern).
