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.
We work closely with the Nanoscale Magnonic Hybrids Research Group, led by Philipp Pirro.

🏅 Prof. Burkard Hillebrands receives academic honors from two Chinese universities
Prof. Dr. Burkard Hillebrands has been awarded two academic honors by leading Chinese universities. Nanjing University appointed him Distinguished Guest Professor, while Hubei University in Wuhan conferred upon him the title of Honorary Professor.
These distinctions recognize Prof. Hillebrands’ longstanding scientific contributions to magnetism, spin dynamics, magnonics, and spintronics, as well as his international engagement in building academic collaborations. While these titles are not research prizes in the narrow sense, they represent significant institutional academic honors and reflect the high international visibility of his work and of research in magnetism and magnonics at RPTU.
The honors underline the importance of scientific exchange between RPTU and partner institutions in China. They provide further opportunities to strengthen collaboration in fundamental and applied research on magnetic materials, spin-wave phenomena, and future information technologies.

🏆 Prof. Dr. Burkard Hillebrands receives the 2026 Dominique Givord Award
We warmly congratulate Prof. Dr. Burkard Hillebrands on receiving the 2026 Dominique Givord Award of the European Magnetism Association (EMA). The Dominique Givord Award recognizes established leaders in magnetism for their scientific excellence and long-standing contributions to advancing magnetism across Europe. Prof. Hillebrands receives the 2026 award for his pioneering contributions to spin dynamics and magnonics, as well as for his dedicated leadership and influential role within the European magnetism community. His scientific achievements include major contributions to Brillouin light scattering spectroscopy and the realization of magnon-based logic devices, helping to establish magnonics as a key field of contemporary magnetism. Prof. Hillebrands served as Full Professor at TU Kaiserslautern and later RPTU Kaiserslautern-Landau from 1995 to 2024, where he now serves as a Senior Professor. He is also a founding member of EMA and served as EMA President from 2019 to 2022. The award will be formally presented at JEMS 2027 in Prague, where Prof. Hillebrands will give a plenary lecture.

"Ultralong-living magnons in the quantum limit" published in Science Advances
A recent collaborative work carried out by researchers from the University of Vienna, University of Colorado Colorado Springs, Oakland University, INNOVENT e.V., Taras Shevchenko National University of Kyiv, and RPTU University Kaiserslautern–Landau has been published in Science Advances: R. O. Serha et al., Sci. Adv. 12, eaee2344 (2026).
The study reports a breakthrough in quantum magnonics by demonstrating magnon lifetimes exceeding 18 μs in ultrapure yttrium iron garnet (YIG) spheres at millikelvin temperatures. This represents an improvement of nearly two orders of magnitude compared to previously known values. As a result, magnons emerge as long-lived quantum excitations, bringing their coherence into the range of superconducting qubits. These findings significantly advance the prospects of using magnons as information carriers in hybrid quantum systems. In particular, such long lifetimes open pathways toward magnon-mediated coupling of distant qubits, quantum memories, and low-loss on-chip interconnects. The work highlights the importance of material purity and low-temperature operation for pushing magnon coherence to unprecedented limits.

📰 Editors’ Suggestion in Physical Review B

Our paper "Enhancement of magnon flux toward a Bose–Einstein condensate" has been selected as an Editors’ Suggestion in Physical Review B (Phys. Rev. B 113, 014409, 2026).
Read the article on APS Journals
In this combined theoretical and experimental study, the authors investigate angle-dependent parametric pumping of magnons in yttrium iron garnet. They demonstrate that the direction of the magnetic field governs magnon scattering pathways via kinetic instability. Parallel pumping lowers the threshold, whereas perpendicular pumping increases the magnon population near the spectral minimum, thereby optimizing the magnon flux into the Bose–Einstein condensate.
