Heisenberg Exchange and Dzyaloshinskii-Moriya Interaction in Ultrathin CoFeB Single and Multilayers
Tobias Böttcher, Kyujoon Lee, Frank Heussner +6
We present results of the analysis of Brillouin Light Scattering (BLS) measurements of spin waves performed on ultrathin single and multirepeat CoFeB layers with adjacent heavy met…
Frequency-Division Multiplexing in Magnonic Logic Networks Based on Caustic-Like Spin-Wave Beams
Frank Heussner, Matthias Nabinger, Tobias Fischer +4
Wave-based data processing by spin waves and their quanta, magnons, is a promising technique to overcome the challenges which CMOS-based logic networks are facing nowadays. The adv…
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…
Optical determination of the exchange stiffness constant in an iron garnet
Keita Matsumoto, Thomas Brächer, Philipp Pirro +7
Brillouin light scattering measurements were performed in the backscattering geometry on a Bi-substituted rare earth iron garnet. We observed two different peaks, one attributed to…
Spin Seebeck effect and ballistic transport of quasi-acoustic magnons in room-temperature yttrium iron garnet films
Timo Noack, Halyna Yu. Musiienko-Shmarova, Thomas Langner +9
We studied the transient behavior of the spin current generated by the longitudinal spin Seebeck effect (LSSE) in a set of platinum-coated yttrium iron garnet (YIG) films of differ…
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…
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…
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…
Temporal evolution of auto-oscillations in a YIG/Pt microdisc driven by pulsed spin Hall effect-induced spin-transfer torque
