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…
Slow-wave based magnonic diode
Matías Grassi, Moritz Geilen, Damien Louis +7
Spin waves, the collective excitations of the magnetic order parameter, and magnons, the associated quasiparticles, are envisioned as possible data carriers in future wave-based co…
Nanoscale spin-wave wake-up receiver
Qi Wang, Thomas Brächer, Morteza Mohseni +4
We present the concept of a passive spin-wave device which is able to distinguish different radio-frequency pulse trains and validate its functionality using micromagnetic simulati…
Integrated magnonic half-adder
Qi Wang, Roman Verba, Thomas Brächer +5
Spin waves and their quanta magnons open up a promising branch of high-speed and low-power information processing. Several important milestones were achieved recently in the realiz…
Spin pinning and spin-wave dispersion in nanoscopic ferromagnetic waveguides
Q. Wang, B. Heinz, R. Verba +8
Spin waves are investigated in Yttrium Iron Garnet (YIG) waveguides with a thickness of 39 nm and widths ranging down to 50 nm, i.e., with aspect ratios thickness over width approa…
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…
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…
