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.
Hannover Messe 2022: Rechenintensive Prozesse in Forschungs- und Entwicklungsprojekten per Cloud beschleunigen
Ist ein Prototyp entwickelt, folgt in Forschung und Entwicklung in der Regel eine zeitaufwändige Test- und Analysephase. Unmengen an Daten aus verteilten Quellen fließen dabei durch komplexe, sich mehrfach wiederholende Rechenprozesse. Diese Phase zu beschleunigen, hat sich das Kaiserslauterer Startup Aithericon auf die Fahne geschrieben. Die Gründer arbeiten an einer cloud-basierten Plattform, die in einer zentralen Umgebung die nötige Infrastruktur zusammenführt und so computergestützte Forschungs- und Entwicklungsprozesse automatisiert. Auf der Hannover Messe stellen die Gründer vom 30. Mai bis 3. Juni ihr Vorhaben am Forschungsstand des Landes Rheinland-Pfalz (Halle 2, Stand B40) vor..
Der Spin schlägt Wellen
We are very happy that our group could contribute to this article for the general public which explains the idea of spin-wave based computing. It recently appeared in the „Bild der Wissenschaft“ (in German).
We are happy to announce the "CHIRON workshop on hybrid spin-wave computing“ (workshop chair: Philipp Pirro).
The workshop will take place in Heraklion, Crete, on 27 April 2022 in a hybrid (digital and physical presence) format. The venue of the workshop is the main amphitheater of the Foundation for Research and Technology – Hellas (FORTH) in Heraklion.
The aim of the workshop is to discuss recent and future concepts for spin-wave computing and the experimental and theoretical methods needed to explore them. Topics include energy efficient spin-wave excitation using the magneto-elastic interaction, large scale spin-wave circuits, nonlinear spin-wave phenomena and the use of novel material systems for magnonics.
ERC Starting Grant to investigate magnonic hardware for neuromorphic computing
Our group member Junior professor Dr. Philipp Pirro has been awarded a 1.5 million euro ERC Starting Grant by the European Research Council (ERC) for five years.
In the ERC-funded project "CoSpiN - Coherent Spintronic Networks for Neuromorphic Computing," spin waves will be used to enable linking and information transfer. The goal is to develop physical building blocks for a novel spintronic network on the nanoscale. In this way, we want to lay the foundation for an artificial brain that is as close as possible to the natural model. The research will take place in the new research building LASE (Laboratory for Advanced Spin Engineering) on the TUK campus.
