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…
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…
Frequency and wavenumber selective excitation of spin waves through coherent energy transfer from elastic waves
Yusuke Hashimoto, Davide Bossini, Tom H. Johansen +3
Using spin-wave tomography (SWaT), we have investigated the excitation and the propagation dynamics of optically-excited magnetoelastic waves, i.e. hybridized modes of spin waves a…
Exact asymptotic behavior of magnetic stripe domain arrays
Tom H. Johansen, Alexey V. Pan, Yuri M. Galperin
The classical problem of magnetic stripe domain behavior in films and plates with uniaxial magnetic anisotropy is treated. Exact analytical results are derived for the stripe domai…
Effect of hydrogen plasma treatment and oxygen deficiency on conducting properties of InO:Sn thin films
V. G. Kytin, V. A. Kulbachinskii, O. V. Reukova +4
Electrical conductivity, Hall effect and magnetoresistance of InO:Sn thin films deposited on a glass substrates at different temperatures and oxygen pressures, as well as t…
