Exchange-mediated directional coupling of short-wavelength spin waves
Zhen Zhu, Roman Verba, Philipp Pirro +2
Miniaturizing magnonic circuits and increasing their processing speed require spin waves with progressively shorter wavelengths. However, conventional directional couplers rely on…
Deeply nonlinear excitation of self-normalised exchange spin waves
Qi Wang, Roman Verba, Björn Heinz +9
Spin waves are ideal candidates for wave-based computing, but the construction of magnetic circuits is blocked by a lack of an efficient mechanism to excite long-running exchange s…
Control of the Bose-Einstein Condensation of Magnons by the Spin-Hall Effect
Michael Schneider, David Breitbach, Rostyslav O. Serha +13
Previously, it has been shown that rapid cooling of yttrium-iron-garnet (YIG)/platinum (Pt) nano structures, preheated by an electric current sent through the Pt layer, leads to ov…
Inverse-design magnonic devices
Qi Wang, Andrii V. Chumak, Philipp Pirro
The field of magnonics offers a new type of low-power information processing, in which magnons, the quanta of spin waves, carry and process data instead of electrons. Many magnonic…
A nonlinear magnonic nano-ring resonator
Qi Wang, Abbass Hamadeh, Roman Verba +5
The field of magnonics, which aims at using spin waves as carriers in data processing devices, has attracted increasing interest in recent years. We present and study micromagnetic…
Temperature dependence of spin pinning and spin-wave dispersion in nanoscopic ferromagnetic waveguides
Björn Heinz, Qi Wang, Roman Verba +10
The field of magnonics attracts significant attention due to the possibility of utilizing information coded into the spin-wave phase or amplitude to perform computation operations…
