Double anticrossings induced by nonlinear magnon interactions
Geil Emdi, Tomosato Hioki, Koujiro Hoshi +3
We observe pump-induced double anticrossings whose gap sizes and center-frequency shifts depend strongly on pump power, indicating a nonlinear mechanism. The anticrossings vanish a…
Electrical detection of parallel parametric amplification and attenuation in / bilayer disk
Geil Emdi, Tomosato Hioki, Koujiro Hoshi +1
We report a systematic quantitative evaluation of parametric amplification gain of magnetization dynamics in ytirrium iron garnet () thin…
Switching of magnon parametric oscillation by magnetic field direction
Sohei Horibe, Hiroki Shimizu, Koujiro Hoshi +3
Parametric oscillation occurs when the resonance frequency of an oscillator is periodically modulated. Owing to time-reversal symmetry breaking in magnets, nonreciprocal magnons ca…
Topological spin Hall effect in antiferromagnets driven by vector Néel chirality
Kazuki Nakazawa, Koujiro Hoshi, Jotaro J. Nakane +2
Spin Hall effect of spin-texture origin is explored theoretically for antiferromagnetic (AF) metals. It is found that a vector chirality formed by the Néel vector gives rise to a t…
Landau Levels from the Bethe Ansatz Equations
K. Hoshi, Y. Hatsugai
The Bethe ansatz (BA) equations for the two-dimensional Bloch electrons in a uniform magnetic field are treated in the weak field limit. We have calculated energies near the lower…
