Phase control of magnon-phonon coupling via magnetic field
Yasuhiro Todaka, Motoki Asano, Isamu Yasuda +3
We study the phase of the coupling between magnons and surface acoustic wave (SAW) phonons in magnetic thin films. The coupling constant changes from a real to a complex number as…
Tellurium Metasurface Beam Splitter with Pulse Laser-Controlled Anisotropy
Takuto Hiraoka, Mizuho Matoba, Yuta Kobayashi +5
Laser-programmable optical anisotropy offers a new route to developing reconfigurable metasurfaces without conventional nanofabrication processes. Here, we demonstrate a lithograph…
Photo-thermal origin of pulse laser induced orientation of crystallographic c axis in Tellurium thin films
Arata Mitsuzuka, Yuta Kobayashi, Takuto Hiraoka +2
Recent studies have shown that the orientation of crystallographic c axis of Tellurium thin films can be controlled using picosecond long laser pulses. This method provides spatial…
Current induced magneto-optical Kerr effect as a probe of Dirac carriers in BiSb alloy
Ryota Miyazaki, Shunzhen Wang, Guanxiong Qu +4
We study the current-induced magneto-optical Kerr effect (MOKE) in BiSb semi-metalic alloys. The MOKE signal is found to be the largest in pure Bi (), exceeding th…
Comments on the formula to extract current-induced torques from the harmonic Hall voltage measurements
Yong-Chang Lau, Yukihiro Marui, Zhendong Chi +2
We examine the formulas commonly used to estimate current-induced spin-orbit torques from harmonic Hall voltage measurements. In particular, we focus on the factor of two discrepan…
