Ultrafast spin-to-charge conversions of antiferromagnetic (111)-oriented -
Huiling Mao, Yuta Sasaki, Yuta Kobayashi +5
Antiferromagnetic - combines outstanding spin-transport properties with magnons in the terahertz (THz) frequency range. However, the THz radiation e…
Spintronic emitters for super-resolution in THz-spectral imaging
Finn-Frederik Stiewe, Tristan Winkel, Yuta Sasaki +9
THz-spectroscopy is an attractive imaging tool for scientific research, especially in life science, offering non-destructive interaction with matter due to its low photon energies.…
Field-enhanced quantum fuctuation in S=1/2 frustrated square lattice
H. Yamaguchi, Y. Sasaki, T. Okubo +9
We present a new model compound with the S = 1/2 frustrated square lattice composed of the charge-transfer salt (o-MePy-V)PF6. Ab initio calculations indicate the formation of an S…
Laser-induced antiferromagnetic-like resonance in amorphous ferrimagnets
S. Mizukami, Y. Sasaki, D. -K. Lee +4
The magnetization dynamics for ferrimagnets at the angular momentum compensation temperature T_A is believed to be analogous to that for antiferromagnets. We investigated the pulse…
Quantification of a propagating spin-wave-packet created by an ultrashort laser pulse in a thin film of magnetic metal
S. Iihama, Y. Sasaki, A. Sugihara +3
Coherent spin-wave generation by focused ultrashort laser pulse irradiation was investigated for a permalloy thin film at micrometer scale using an all-optical space and time-resol…
Reflection and refraction process of spinwave in a ferromagnet/frustrated ferromagnet junction system
Yuta Sasaki, Hiroaki T. Ueda
Frustration introduces a nontrivial dispersion relation of spinwave even in a ferromagnetic phase in a spin system. We study the reflection and refraction process of spinwaves in t…
Active electromagnetic metamaterial based on spin torque oscillators
Gen Tatara, Hiroaki T. Ueda, Katsuhisa Taguchi +3
We propose theoretically an active material for electromagnetic radiation with frequency of GHz by use of spin-torque oscillators. The origin of the amplification is the energy sup…
