All-optical magnetization reversal via x-ray magnetic circular dichroism
Kihiro T. Yamada, Akira Izumi, Tetsuya Ikebuchi +15
Light polarization is one of the most fundamental features, equivalent to energy and coherence. Magnetism changes light polarization, and vice versa. The irradiation of intense cir…

X-ray free-electron laser observation of giant and anisotropic magnetostriction in -O at 110 Tesla
Akihiko Ikeda, Yuya Kubota, Yuto Ishii +18
In strong magnetic fields beyond 100 T, the significant Zeeman energy competes with the lattice interactions, where a considerable magnetostriction is expected. However, the micros…

A simple method to find temporal overlap between THz and X-ray pulses using X-ray-induced carrier dynamics in semiconductors
Yuya Kubota, Takeshi Suzuki, Shigeki Owada +5
X-ray-induced carrier dynamics in silicon and gallium arsenide were investigated through intensity variations of transmitted terahertz (THz) pulses in the pico to microsecond time…
