Preliminary discussion and assignment of topics


This seminar deals with spin-related phenomena in solid state physics.

The focus of the seminar will be on
1. spin dynamics in paramagnetic and exchange coupled systems
2. spin mechanics
3. spin currents and spin pumping

All topics have substantial overlap with magnetism-related research activities at the WMI and the TUM physics department. Seminar talks can be given either in English or in German.

The seminar is relevant for the special courses on "Magnetism and Spintronics". It is suitable for bachelor and master students in the 6. semester and higher.

(Spin-abhängige Effekte in Festkörpern stehen im Fokus dieses Seminars. Dabei sollen einerseits spin-kalorische Phänomene diskutiert werden, also der Spin- bzw. Ladungstransport in Proben, die einem Temperaturgradienten ausgesetzt sind. Andererseits werden wir uns mit Spindynamik und Spin-Strömen bzw. dem Spin-Pumpen-Effekt beschäftigen. Der Spin-Pumpen-Effekt erlaubt die Erzeugung reiner Spintröme, die für die Grundlagenforschung und für Spin-Elektronik sehr interessant sind.)

Topics for seminar talks in WS 2013/2014:
  1. Dynamic of paramagnetic spin systems (Rabi ocillations, Hahn echoes and further pulse sequences used in pulsed EPR) (Literature: A. Schweiger and G Jeschke, Principles of pulse electron paramagnetic resonance, M. H. Levitt, Spin dynamics)

  2. Spin dynamics in exchange coupled spin systems (Landau Lifschitz Gilbert equation including damping) (Literature: Stancil, Morrish, Chikazumi)

  3. Magnon basics [magnon dispersion, propagation length, magnon modes] (Literature: Sparks, Demokritov, Hillebrands)

  4. Spin mechanics - the dynamic properties (M. Weiler et al., Phys. Rev. Lett. 106, 117601 (2011), L. Dreher et al., Phys. Rev. B 86, 134415 (2012))

  5. Acoustic spin pumping (Literature: Uchida et al., Nature Mater. 10, 737 (2011), Weiler PRL 106, 176601 (2012))
