Enhancement of magnon flux toward a Bose-Einstein condensate
Franziska Kühn, Matthias R. Schweizer, Tamara Azevedo +5
We present a combined theoretical and experimental study of angle-dependent parametric pumping of magnons in Yttrium Iron Garnet films, with a focus on the mechanisms that transfer…
Unified theory of magnetization temperature dependence in ferrimagnets
Rostyslav O. Serha, Anna Pomyalov, Andrii V. Chumak +1
Recent advancements in spintronics and fundamental physical research have brought increased attention to the rare-earth-based magnetically ordered materials. One of the important p…
Precritical anomalous scaling and magnetization temperature dependence in cubic ferromagnetic crystals
Igor Kolokolov, Victor S. L'vov, Anna Pomyalov
Recent developments in spintronics have drawn renewed attention to the spin dynamics of cubic ferromagnetic crystals EuO and EuS. These ferromagnets have the simplest possible magn…
Local temperature control of magnon frequency and direction of supercurrents in a magnon Bose-Einstein condensate
Matthias R. Schweizer, Franziska Kühn, Victor S. L'vov +4
The creation of temperature variations in magnetization, and hence in the frequencies of the magnon spectrum in laser-heated regions of magnetic films, is an important method for s…
Bose-Einstein condensation in systems with flux equilibrium
Victor S. L'vov, Anna Pomyalov, Sergey V. Nazarenko +4
We consider flux equilibrium in dissipative nonlinear wave systems subject to external energy pumping. In such systems, the elementary excitations, or quasiparticles, can create a…
Correlation-enhanced interaction of a Bose-Einstein condensate with parametric magnon pairs and virtual magnons
Victor S. L'vov, Anna Pomyalov, Dmytro A. Bozhko +2
Nonlinear interactions are crucial in science and engineering. Here, we investigate wave interactions in a highly nonlinear magnetic system driven by parametric pumping leading to…
