Schülerinnentag 2015

On October, 1st, female students from high schools all over Rhineland-Palatinate visited our labs in order to get a general understanding about studying physics. They came to our University in the context of the "Schülerinnen-Tag. Natur Wissenschaft Technik". We provided the girls with a lively program: Interactive experiments, a lab-tour, and a short sample lecture on magnetism and our research.

We enjoyed to have them with us and hope to see them in the future as fellow students!


Schülerinnentag 2015 in our group




ICM 2015 Conference, Barcelona

Our PhD student Dmytro Bozhko has been awarded the Best Poster Award of Monday's Session on the ICM 2015 conference in Barcelona. He and his coworkers presented the latest results on their research on Magnon Bose-Einstein condensates.

Our review article in Nature Physics on magnon spintronics is online:

Magnon spintronics is the field of spintronics concerned with structures, devices and circuits that use spin currents carried by magnons. The use of magnons allows the implementation of novel wave-based computing technologies free from the drawbacks inherent to modern electronics, such as dissipation of energy due to Ohmic losses. Logic circuits based on wave interference and nonlinear wave interaction can be designed with much smaller footprints compared with conventional electron-based logic circuits.

In our review we introduce the basic properties of magnons and their handling and we discuss the inter-conversion between magnon currents and electron-carried spin and charge currents. In addition, concepts and experimental studies of magnon-based computing circuits are presented.
