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.…
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…
Large magnetostriction and first-order phase transition induced by ultrahigh magnetic fields in VO
Yuto Ishii, Akihiko Ikeda, Yasuhiro. H. Matsuda
VO exhibits the metal-insulator transition (MIT) at around 150 K with the formation of vanadium-vanadium (V-V) dimers. We measured the magnetostriction of VO…
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…
Experimental and Numerical Studies of the Collapse of Dense Clouds Induced by Herbig-Haro Stellar Jets
Marin Fontaine, Clotilde Busschaert, Yaniss Benkadoum +9
This study investigates the influence of Herbig-Haro jets on initiating star formation in dense environments. When molecular clouds are nearing gravitational instability, the impac…
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…
