AKjDPG 3: PhD Symposium: Ultrafast spin-lattice interactions (joint session MA/AKjDPG)

Dienstag, 13. März 2018, 09:30–13:15, H 1012

The immensely fascinating field of magnetism research has branched into many lively communities such as spintronics, ultrafast demagnetization, all-optical switching, multiferroic materials, domain walls, magnetic textures and spin caloritronics just to mention a few. All of these hot research topics share that the relevant interacting magnetic moments are arranged within the framework of an atomic lattice which itself interacts with the spin system. The lattice thus does not only influence the geometrical arrangement of the magnetic moments but also serves as a major bath for energy, entropy and most importantly also angular momentum transfer within the studied systems. The symposium aims at exchanging ideas and at fostering the discussion about the effects of the spin- lattice interaction among various areas of magnetism research. We highly welcome contributions that explain basic mechanisms and results of the spin-lattice interaction from all communities. Spin-lattice interaction can be considered as one of the prototypical coupling mechanisms within correlated materials and the condensed matter research in general. It is a very timely topic as many applications in future information technology such as spintronic-devices, heat assisted magnetic recording, implementations of the Spin-Seebeck, all-optical magnetization switching greatly benefit from an understanding of this basic effect.

Organized by: Alexander von Reppert (U. Potsdam), Vivek Unikandanunni, (U. Stockholm), Kumar Neeraj, (U. Stockholm), Neha Jha (U. Greifswald), Tobias Wimmer, (Walther Meißner Institute München), Kamil Bobowski (FU Berlin), Markus Gleich (FU Berlin).
