Experimental Realization of a Passive GHz Frequency-Division Demultiplexer for Magnonic Logic Networks
Frank Heussner, Giacomo Talmelli, Moritz Geilen +9
The emerging field of magnonics employs spin waves and their quanta, magnons, to implement wave-based computing on the micro- and nanoscale. Multi-frequency magnon networks would a…
Realization of a spin wave switch based on the Spin-Transfer-Torque effect
Thomas Meyer, Thomas Brächer, Frank Heussner +7
We investigate the amplification of externally excited spin waves via the Spin-Transfer-Torque (STT) effect in combination with the Spin-Hall-Effect (SHE) employing short current p…
Determination of the spin Hall angle in single-crystalline Pt films from spin pumping experiments
Sascha Keller, Laura Mihalceanu, Matthias R. Schweizer +12
We report on the determination of the spin Hall angle and the identification of the role of the interface roughness for the inverse spin Hall effect (ISHE) in ultra-clean, defect-r…
Experimental investigation of the temperature-dependent magnon density and its influence on studies of spin-transfer-torque-driven systems
Thomas Meyer, Thomas Brächer, Frank Heussner +7
We present the temperature dependence of the thermal magnon density in a thin ferromagnetic layer. By employing Brillouin light scattering and varying the temperature, an increase…
Spin-Wave versus Joule Heating in Spin-Hall-Effect/Spin-Transfer-Torque Driven Cr/Heusler/Pt Waveguides
T. Meyer, T. Brächer, F. Heussner +7
We present a time-resolved study of the DC-current driven magnetization dynamics in a microstructured Cr/Heusler/Pt waveguide by means of Brillouin light scattering. A reduction of…
Bose-Einstein Condensation of Quasi-Particles by Rapid Cooling
M. Schneider, T. Brächer, D. Breitbach +18
The fundamental phenomenon of Bose-Einstein Condensation (BEC) has been observed in different systems of real and quasi-particles. The condensation of real particles is achieved th…
