Welcome to the homepage of the magnetism group!


Prof. Hillebrands will offer a block course on magnonics from April, 7-10, which will give an insight into the basics of spin dynamics and magnonics as well as into our current research topics and experimental setups.
More information can be obtained either by contacting any of our group members or by following this link:

Magnonics at CeBIT 2015

The magnon transistor technology can serve as a key feature to enable the development of magnon-based wave logic computing devices.

Our group presented a prototype of such a magnon transistor to the international public at the CeBIT 2015 exhibition, the world's largest trade fair on information technology.

Further information is available at CeBIT 2015: Magnon Transistor


Demonstration of the magnon transistor to Prof. Dr. Thomas Deufel, Under-Secretary, Ministery for Education, Science, Further Education and Culture of the State Rhineland-Palatinate:

STeP conclusion meeting

Conca (TU Kaiserslautern), J. Rühl (LTI Drives), Dr. B. Leven (TU Kaiserslautern), Prof. Dr. B. Hillebrands (TU Kaiserslautern), Dr. J. Gerber (director of the magnetic industry association INNOMAG), Dr. R. Slatter (Sensitec, CEO).


The conclusion meeting for the Spin Technology Platform (STeP) took place on February, 12, at the facilities of our industrial collaborator Sensitec in Mainz. Together with the Johannes Gutenberg University in Mainz, STeP aims to the development of new concepts and measurement methods for the magnetic sensor technology. STeP is a clear example of technology transfer between universities and industries, where relevant results on lab level are prepared to be converted into real applications. The magnetic sensor technology finds application in the automotive industry, in robotics or for industrial automation processes.

During the meeting, the main scientific results were presented to a delegation of people from the industry and politics. In the center of the photo above, a model of the elevators system of the Taipei building in Taiwan is shown. This model explains an example of a real application of magnetic sensors for positioning and contains the same sensors used in the actual building in Taipei (courtesy of ELGO Electronics, developer of this system).

In addition, the partner project TT-DINEMA (Technology Transfer Service Centre for New Materials) was also presented. The aim of the TT-DINEMA project is to establish a service center for new material concepts for various fields, ranging from solar technology through medical technology to thermoelectrics.
