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…
Nonlinear enhancement of coherent magnetization dynamics
Mehrdad Elyasi, Kei Yamamoto, Tomosato Hioki +4
Magnets are interesting materials for classical and quantum information technologies. However, the short decoherence and dephasing times that determine the scale and speed of infor…
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…
Composition-tunable magnon-polaron anomalies in spin Seebeck effects in epitaxial BiYFeO films
Takashi Kikkawa, Koichi Oyanagi, Tomosato Hioki +5
We have investigated hybridized magnon-phonon excitation (magnon polarons) in spin Seebeck effects (SSEs) in BiYFeO (BiYIG; , , and $…
Roadmap on Spin-Wave Computing
A. V. Chumak, P. Kabos, M. Wu +113
Magnonics is a field of science that addresses the physical properties of spin waves and utilizes them for data processing. Scalability down to atomic dimensions, operations in the…
Magnon polarons in the spin Peltier effect
Reimei Yahiro, Takashi Kikkawa, Rafael Ramos +4
We report the observation of anomalous peak structures induced by hybridized magnon-phonon excitation (magnon polarons) in the magnetic field dependence of the spin Peltier effect…
Snell's law for spin waves at a 90-degree domain wall
Tomosato Hioki, Rei Tsuboi, Tom. H. Johansen +2
We report experimental observation of the refraction and re ection of propagating magnetostatic spin waves crossing a 90-degree domain wall (DW) in terms of time-resolved magneto-o…
Room temperature and low-field resonant enhancement of spin Seebeck effect in partially compensated magnets
R. Ramos, T. Hioki, Y. Hashimoto +7
Resonant enhancement of spin Seebeck effect (SSE) due to phonons was recently discovered in Y3Fe5O12 (YIG). This effect is explained by hybridization between the magnon and phonon…
Thermographic measurements of the spin Peltier effect in metal/yttrium-iron-garnet junction systems
Shunsuke Daimon, Ken-ichi Uchida, Ryo Iguchi +2
The spin Peltier effect (SPE), heat-current generation due to spin-current injection, in various metal (Pt, W, and Au single layers and Pt/Cu bilayer)/ferrimagnetic insulator (yttr…
Thermal imaging of spin Peltier effect
Shunsuke Daimon, Ryo Iguchi, Tomosato Hioki +2
When a charge current is applied to a junction comprising two different conductors, its temperature increases or decreases depending on the direction of the charge current. This ph…
