Welcome to the magnetism group!
We are dedicated to cutting-edge research in the field of magnonics and related areas combined with excellent teaching.
Magnonics is a subfield of spintronics, which addresses the utilization of the spin degree of freedom for applications in information and communication technologies. We study „magnetic waves“, which are spin waves and their quanta called magnons, and we address new fundamental phenomena and their potential for applications. A particular focus is on macroscopic quantum phenomena such as supercurrents and their utilization, as well as on the development of magnonic devices for the information technology.
Our research is embedded in the Collaborative Research Center 173 „Spin+X“ funded by the Deutsche Forschungsgemeinschaft, as well as by several national, European and international projects. We offer opportunities for qualification in the frames of student assistantships, bachelor, master diploma and PhD projects in an international environment.
Magnonic devices have the potential to revolutionize the electronics industry. Qi Wang and Andrii Chumak of the University of Vienna and Philipp Pirro of TU Kaiserslautern, have significantly accelerated the design of versatile magnonic devices using an optimization algorithm. Their "inverse design" of magnonic devices is now published in Nature Communications.

“The 2021 Magnonics Roadmap” has been accepted for publication in Journal of Physics: Condensed Matter. This is a topical review paper in which world’s leading experts in the field of magnonics review and discuss the current status, as well as present their vision of future perspectives of this rather young research field.

"A magnonic directional coupler for integrated magnonic half-adders" is published in Nature Electronics
In a collaboration with our former group member Prof. Andrii Chumak (now at the University of Vienna), we have succeeded in constructing the basic building block for a novel computer circuit: Instead of electrons, magnons in nanoformat take over the transfer of information. The so-called "magnonic half adder", which is described in the journal Nature Electronics, requires only three nanowires and much less energy than modern computer chips.
