Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Chiral phonons probed by X rays
Hiroki Ueda, Mirian García-Fernández, Stefano Agrestini +5
The concept of chirality is of great relevance in nature, from chiral molecules such as sugar to parity transformations in particle physics. In condensed matter physics, recent stu…
Conical spin order with chiral quadrupole helix in CsCuCl3
Hiroki Ueda, Elizabeth Skoropata, Max Burian +5
Here we report a resonant x-ray diffraction (RXD) study at the Cu L3 edge on the multi-chiral system CsCuCl3, exhibiting helical magnetic order in a chiral crystal structure. RXD i…
Optical excitation of electromagnons in hexaferrite
Hiroki Ueda, Hoyoung Jang, Sae Hwan Chun +11
Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years,…
4D visualization of the photoexcited coherent magnon by an X-ray free electron laser
Hoyoung Jang, Hiroki Ueda, Hyeong-Do Kim +12
X-ray free electron lasers (XFEL) create femtosecond X-ray pulses with high brightness and high longitudinal coherence allowing to extend X-ray spectroscopy and scattering techniqu…
Magnetic field dependent cycloidal rotation in pristine and Ge doped CoCrO
N Ortiz Hernandez, S Parchenko, J R L Mardegan +11
We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films of CoGeCrO (Ge-CCO) and CoCrO (CC…
