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

The focus of the seminar will be on
- Antiferromagnets
- Skyrmions
- Pure spin currents

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

Topics for seminar talks in WS 2017/2018:

Skyrmionics

  1. Magnetic skyrmions and their current-driven dynamics in ultrathin metallic ferromagnets (Literature: Woo, S. et al., Nat Mater 15, 501–506 (2016)).
  2. Scanned probe imaging of nanoscale magnetism at cryogenic temperatures with a single-spin quantum sensor. (Literature: Pelliccione, M. et al., Nat Nano 11, 700–705 (2016)).
  3. Current-induced skyrmion generation and dynamics in symmetric bilayers (Literature: Hrabec et al., Nat. Com. 8, 15765 (2017)).
  4. Magnetic antiskyrmions above room temperature in tetragonal Heusler materials (Literature: Nayak et al., Nature 548, 561 (2017)).

Antiferromagnetic Spintronics:

  1. Magnetization switching by spin–orbit torque in an antiferromagnet–ferromagnet bilayer system (Literature: Fukami et al., Nature Materials 4566 (2016)).
  2.  All-oxide–based synthetic antiferromagnets exhibiting layer-resolved magnetization reversal
    (Literature: Chen et al., 357, 191 (2017)).
  3. Writing and Reading antiferromagnetic Mn2Au: Néel spin-orbit torques and large anisotropic magnetoresistance (Literature Bodnar et al., arXiv 1706.02482)

Pure spin currents mediated by magnons amd electrons:

  1. Magnon planar Hall effect and anisotropic magnetoresistance in a magnetic insulator (Literature: Liu et al.,  Phys. Rev. B 95, 140402 (2017)).
  2. Control and local measurement of the spin chemical potential in a magnetic insulator
    (Literature: Du et al., Science  357, 195 (2017)).
  3. Current-induced switching in a magnetic insulator (Literature: Avci, et al., Nat Mater 16, 309 (2017)).
  4. Enhanced spin–orbit torques by oxygen incorporation in tungsten films (Literature: Demasius et al., Nat. Com. 7, 10644 (2016)).
