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 $…
Excitation and relaxation dynamics of spin-waves triggered by ultrafast photo-induced demagnetization in a ferrimagnetic insulator
Yusuke Hashimoto, Koji Sato, Tom H. Johansen +1
Excitation and propagation dynamics of spin waves in an iron-based garnet film under out-of-plane magnetic field were investigated by time-resolved magneto-optical imaging. The exp…
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…
180-degree phase shift of magnetoelastic waves observed by phase-resolved spin-wave tomography
Yusuke Hashimoto, Tom H. Johansen, Eiji Saitoh
We have investigated optically-excited magnetoelastic waves by phase-resolved spin-wave tomography (PSWaT). PSWaT reconstructs dispersion relation of spin waves together with their…
Phase-resolved Spin-Wave Tomography
Yusuke Hashimoto, Tom H. Johansen, Eiji Saitoh
The propagation dynamics of spin waves are represented by their dispersion relations. Recently, we have developed a method, called spin-wave tomography (SWaT), to obtain dispersion…
