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 WS 2020/21:

Skyrmionics

1. 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 )
2. Current-induced dynamics of skyrmion strings (T. Yokouchi, Science Advances 10, eaat1115 (2018), https://doi.org/10.1126/sciadv.aat1115)
3. Transformation between meron and skyrmion topological spin textures in a chiral magnet (Yu et al., Nature 564, 95 (2018))
4. Current-Induced Modulation of the Interfacial Dzyaloshinskii-Moriya Interaction (Kato et al., Phys. Rev. Lett. 122, 257205 (2019))
5. Room-temperature stabilization of antiferromagnetic skyrmions in synthetic antiferromagnets (Legrand et al. Nature Materials 19, 34 (2019))
6. Electrical detection of single magnetic skyrmions in metallic multilayers at room temperature (Maccariello et al. Nature Nanotechnology 13, 233 (2018))

All-electrical magnon transport:

1. Propagation Length of Antiferromagnetic Magnons Governed by Domain Configurations (Ross et al., Nano Lett 20, 306 (2020))
2. Impact of electromagnetic fields and heat on spin transport signals in YIG (Y3Fe5O12) (Cramer et al., Phys. Rev. B 100 094439 (2019))
3. Interface-driven chiral magnetism and current-driven domain walls in insulating magnetic garnets (Avci et al., Nature Nanotechnology 14, 561 (2019))
4. Probing the Source of the Interfacial Dzyaloshinskii-Moriya Interaction Responsible for the Topological Hall Effect in Metal/Tm3Fe5O12 Systems (Lee et al., Phys. Rev. Lett. 124, 107201 (2020))
5. Current-driven magnetic domain-wall logic (Luo et al. Nature 579, 214 (2020))

Complex magnon dynamics:

1. 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 )
2. Bistability of Cavity Magnon Polaritons (Wang et al., Phys. Rev. Lett. 120, 057202 (2018))
3. Microwave control of thermal-magnon spin transport (J. Liu, Phys. Rev. B 99, 054420 (2019), https://doi.org/10.1103/PhysRevB.99.054420)
4. Chiral Spin-Wave Velocities Induced by All-Garnet Interfacial Dzyaloshinskii-Moriya Interaction in Ultrathin Yttrium Iron Garnet Films (Wang et al., Physical Review Letters 124, 027203 (2020))
