Dear participants,

the preliminary discussion and the assignment of topics will take place on Thursday April 28^th and May 5^th at 2pm in the WMI Seminar room (room# 039). Please also find a list of topics in this announcement. 

See you on Thursdays!

     Matthias Althammer on behalf of the seminar organizers 

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.
