Low magnon damping of a EuSe film down to millikelvin temperatures
Rostyslav O. Serha, Jan Hofer, Khrystyna O. Levchenko +4
The rapid development of quantum magnonics over the past decade has created a demand for magnetic materials that keep their magnon losses low at millikelvin temperatures and add fu…
Effects of spin-orbit torque on the ferromagnetic and exchange spin wave modes in ferrimagnetic CoGd alloy
B. Divinskiy, G. Chen, S. Urazhdin +2
We use micro-focus Brillouin light scattering spectroscopy to study the effects of spin-orbit torque on thermal spin waves in almost angular-momentum compensated ferrimagnetic CoGd…
Brillouin Light Scattering of Spin Waves Inaccessible with Free-Space Light
R. Freeman, R. Lemasters, T. Kalejaiye +8
Micro-focus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentu…
Sub-micrometer near-field focusing of spin waves in ultrathin YIG films
B. Divinskiy, N. Thiery, L. Vila +5
We experimentally demonstrate tight focusing of a spin wave beam excited in extended nanometer-thick films of Yttrium Iron Garnet by a simple microscopic antenna functioning as a s…
Emission of coherent propagating magnons by insulator-based spin-orbit torque oscillators
M. Evelt, L. Soumah, A. B. Rinkevich +8
We experimentally demonstrate generation of coherent propagating magnons in ultra-thin magnetic-insulator films by spin-orbit torque induced by dc electric current. We show that th…
Route toward high-speed nano-magnonics
B. Divinskiy, V. E. Demidov, S. O. Demokritov +2
We study experimentally the possibility to utilize pulses of pure spin current, produced via the nonlocal spin injection mechanism, to generate short packets of spin waves propagat…
The Ginzburg-Landau model of Bose-Einstein condensation of magnons
B. A. Malomed, O. Dzyapko, V. E. Demidov +1
We introduce a system of phenomenological equations for Bose-Einstein condensates of magnons in the one-dimensional setting. The nonlinearly coupled equations, written for amplitud…
Bose-Einstein condensation of magnons under incoherent pumping
A. V. Chumak, G. A. Melkov, V. E. Demidov +3
Bose-Einstein condensation in a gas of magnons pumped by an incoherent pumping source is experimentally studied at room temperature. We demonstrate that the condensation can be ach…
