Magneto-optical Kerr effect measurements under bipolar pulsed magnetic fields
Soichiro Yamane, Sota Nakamura, Atsutoshi Ikeda +3
The magneto-optical Kerr effect (MOKE) is a powerful probe of magnetism. Its contact-free optical nature makes it potentially well suitable for measurements under pulsed magnetic f…
Development of ultra-high efficiency soft X-ray angle-resolved photoemission spectroscopy equipped with deep prior-based denoising method
Kohei Yamagami, Yuichi Yokoyama, Yuta Sumiya +3
Soft X-ray angle resolved photoemission spectroscopy (SX-ARPES) is one of the most powerful spectroscopic techniques to visualize the three-dimensional bulk electronic structure in…
Unified Description of Spin-Lattice Coupling and Thermodynamics in the Pyrochlore Heisenberg Antiferromagnet
Masaki Gen, Hidemaro Suwa, Shusaku Imajo +6
We study an extended model to describe the spin-lattice coupling, incorporating individual vibrations of bonds and atomic sites alongside distance-dependent exchange interactions.…
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…
Crystal-field magnetostriction of the spin ice under ultrahigh magnetic fields
Nan Tang, Masaki Gen, Martin Rotter +9
We present a comprehensive study of the magnetoelastic properties of the Ising pyrochlore oxide HoTiO, known as spin ice, by means of high-field magnetostriction…
A review on magnetic field induced spin crossover in LaCoO up to 600 T
Akihiko Ikeda, Yasuhiro H. Matsuda, Keisuke Sato +1
\lco{} is known for its two-step spin crossover as a function of temperature. Despite efforts spanning over half a century, the origin of this phenomenon is still debated, particul…
