Arbeitsgruppe Prof. Hillebrands

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.

"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.

Review: "Opportunities and challenges for spintronics in the microelectronics industry“ is published in Nature Electronics
Together with many colleagues from all over Europe, we review recent developments in spintronics that could soon have an impact on the microelectronics and information technology industry. We highlight and explore four key areas: magnetic memories, magnetic sensors, radio-frequency and microwave devices, and logic and non-Boolean devices. We also discuss the challenges—at both the device and the system level—that need be addressed in order to integrate spintronic materials and functionalities into mainstream microelectronic platforms.
