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

The focus of the seminar will be on
- 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 WS2019/2020:

Skyrmionics

  1. Observation of two independent skyrmion phases in a chiral magnetic material (Chacon et al., Nature Physics 14, 936 (2018) https://doi.org/10.1038/s41567-018-0184-y )
  2. Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction (Dovzhen et al., Nature Communications 9, 2712 (2018) https://doi.org/10.1038/s41467-018-05158-9 )
  3. Fast current-driven domain walls and small skyrmions in a compensated ferrimagnet (Caretta et al., Nature Nanotechnology (2018) https://doi.org/10.1038/s41565-018-0255-3 )
  4. Current-induced dynamics of skyrmion strings (T. Yokouchi, Science Advances 10, eaat1115 (2018), https://doi.org/10.1126/sciadv.aat1115)

All-electrical magnon transport:

  1. Nonlinear spin conductance of yttrium iron garnet thin films driven by large spin-orbit torque (Thiery et al., Physical Review B 97, 060409 (2018) https://doi.org/10.1103/PhysRevB.97.060409 )
  2. Efficient injection and detection of out-of-plane spins via the anomalous spin Hall effect in permalloy nanowires, (Das et al., Nano Lett 18, 5633 https://doi.org/10.1021/acs.nanolett.8b02114 )
  3. Observation of magnon mediated current drag in Pt/YIG/Pt trilayers, (Li et al. Nature Comm. 7, 10858 (2016), https://doi.org/10.1038/ncomms10858)
  4. Modulation of magnon spin transport in a magnetic gate transistor (K. S. Das, arXiv: 1909.03775, https://arxiv.org/abs/1909.03775)

Complex magnon dynamics:

  1. Supercurrent in a room-temperature Bose–Einstein magnon condensate (Bozhko et al., Nature Physics 12, 1057 (2016), https://doi.org/10.1038/nphys3838 )
  2. Magnon-magnon interactions in a room-temperature magnonic Bose-Einstein condensate (Dzyapko et al., Physical Review B 96, 064438, (2017), https://doi.org/10.1103/PhysRevB.96.064438 )
  3. Enhanced spin pumping into superconductors provides evidence for superconducting pure spin currents (K.-R. Jeon Nature Materials 17,499 (2018), https://doi.org/10.1038/s41563-018-0058-9 )
  4. Microwave control of thermal-magnon spin transport (J. Liu, Phys. Rev. B 99, 054420 (2019), https://doi.org/10.1103/PhysRevB.99.054420)
  5. Two-Fluid Theory for Spin Superfluidity in Magnetic Insulators (B. Flebus, Phys. Rev. Lett. 116, 117201 (2016), https://doi.org/10.1103/PhysRevLett.116.117201)
