Student for Master Thesis (f/m)

The idea of the racetrack memory [1] drives us to investigate the motion dynamics of magnetic domain walls. These domain walls are meant to serve as bits in this novel storage device and are driven by an electrical current in a nanostrip. Current research focuses on the increase of domain wall velocity in order to increase read and write rates as well as on an efficiency enhancement of converting a charge current into a motion of the magnetic domain wall.

Since the idea in 2008, several breakthroughs have been achieved and the design evolved from a 1.0 to a 4.0 version solving major obstacles [2]. In the latest version, synthetic antiferromagnetic structures show very fast domain wall motion while the structure itself does not exhibit stray fields and is insensitive to magnetic fields. This is technologically highly interesting and paved the way to more efficient and better controllable antiferromagnetic domain wall motion. We recently extended our research to ferrimagnetic systems in which two distinct magnetic materials couple antiferromagnetically [3].
