Transient grating spectroscopy on a DyCo thin film with femtosecond extreme ultraviolet pulses
Victor Ukleev, Ludmila Leroy, Riccardo Mincigrucci +11
Surface acoustic waves (SAWs) are excited by femtosecond extreme ultraviolet (EUV) transient gratings (TGs) in a room-temperature ferrimagnetic DyCo alloy. TGs are generated by…
Combined theoretical and experimental study of the Moiré dislocation network at the SrTiO-(La,Sr)(Al,Ta)O interface
Chiara Ricca, Elizabeth Skoropata, Marta D. Rossell +3
Recently a highly ordered Moiré dislocation lattice was identified at the interface between a \ce{SrTiO3} (STO) thin film and the (LaAlO)(SrTaAlO) (LSAT…
Transient non-collinear magnetic state for all-optical magnetization switching
Sergii Parchenko, Antoni Frej, Hiroki Ueda +12
Resonant absorption of a photon by bound electrons in a solid can promote an electron to another orbital state or transfer it to a neighboring atomic site. Such a transition in a m…
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…
Antiferromagnetic spin canting and Magnetoelectric Multipoles in h-YMnO
M. Ramakrishnan, Y. Joly, Q. N. Meier +7
Hexagonal YMnO is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We obs…
Effect of intense x-ray free-electron laser transient gratings on the magnetic domain structure of Tm:YIG
Victor Ukleev, Max Burian, Sebastian Gliga +13
Magnetic patterns can be controlled globally using fields or spin polarized currents. In contrast, the local control of the magnetization on the nanometer length scale remains chal…
Unusual ferrimagnetism in CaFe2O4
Hiroki Ueda, Elizabeth Skoropata, Cinthia Piamonteze +7
Incomplete cancellation of collinear antiparallel spins gives rise to ferrimagnetism. Even if the oppositely polarized spins are owing to the equal number of a single magnetic elem…
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…
Exchange scaling of ultrafast angular momentum transfer in 4 antiferromagnets
Y. W. Windsor, S-E. Lee, D. Zahn +11
Ultrafast manipulation of the magnetic state of matter bears great potential for future information technologies. While demagnetisation in ferromagnets is governed by dissipation o…
Hard X-ray Transient Grating Spectroscopy on Bismuth Germanate
Jeremy R. Rouxel, Danny Fainozzi, Roman Mankowsky +44
Optical-domain Transient Grating (TG) spectroscopy is a versatile background-free four-wave-mixing technique used to probe vibrational, magnetic and electronic degrees of freedom i…
Ultrafast electron localization in a correlated metal
Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27
Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…
Continuous magnetic phase transition in artificial square ice
O. Sendetskyi, V. Scagnoli, N. Leo +6
Critical behavior is very common in many fields of science and a wide variety of many-body systems exhibit emergent critical phenomena. The beauty of critical phase transitions lie…
Field-induced double spin spiral in a frustrated chiral magnet
M. Ramakrishnan, E. Constable, A. Cano +14
We report the direct observation of a magnetic-feld induced long-wavelength spin spiral modulation in the chiral compound Ba3TaFe3Si2O14. This new spin texture emerges out of a chi…
