Element-specific ultrafast lattice dynamics in FePt nanoparticles
Diego Turenne, Igor Vaskivskiy, Klaus Sokolowski-Tinten +14
Light-matter interaction at the nanoscale in magnetic alloys and heterostructures is a topic of intense research in view of potential applications in high-density magnetic recordin…
State-resolved ultrafast charge and spin dynamics in [Co/Pd] multilayers
Loïc Le Guyader, Daniel J. Higley, Matteo Pancaldi +17
We use transient absorption spectroscopy with circularly polarized x-rays to detect laser-excited hole states below the Fermi level and compare their dynamics with that of unoccupi…
Tracking the Ultrafast Non-Equilibrium Energy Flow between Electronic and Lattice Degrees of Freedom in Crystalline Nickel
P. Maldonado, T. Chase, A. H. Reid +9
Femtosecond laser excitation of solid-state systems creates non-equilibrium hot electrons that cool down by transferring their energy to other degrees of freedom and ultimately to…
Triply degenerate nodal points in RERhGe (RE=Y, La, Lu)
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
As a new type of fermions without counterpart in high energy physics, triply degenerate fermions show exotic physical properties, which are represented by triply degenerate nodal p…
Terahertz-driven magnetism dynamics in the orthoferrite DyFeO3
A. H. M. Reid, Th. Rasing, R. V. Pisarev +2
Terahertz driven magnetization dynamics are explored in the orthoferrite DyFeO3. A high-field, single cycle THz pulse is used to excite magnon modes in the crystal together with ot…
Stacking order dynamic in the quasi-two-dimensional dichalcogenide 1T-TaS probed with MeV ultrafast electron diffraction
L. Le Guyader, T. Chase, A. Reid +7
Transitions between different charge density wave (CDW) states in quasi-two-dimensional materials may be accompanied also by changes in the inter-layer stacking of the CDW. Using M…
Magnetic switching in granular FePt layers promoted by near-field laser enhancement
Patrick W. Granitzka, Emmanuelle Jal, Loïc Le Guyader +20
Light-matter interaction at the nanoscale in magnetic materials is a topic of intense research in view of potential applications in next-generation high-density magnetic recording.…
Interface-Induced Phenomena in Magnetism
Frances Hellman, Axel Hoffmann, Yaroslav Tserkovnyak +24
This article reviews static and dynamic interfacial effects in magnetism, focusing on interfacially-driven magnetic effects and phenomena associated with spin-orbit coupling and in…
Beyond a phenomenological description of magnetostriction
A. H. Reid, X. Shen, P. Maldonado +28
We use ultrafast x-ray and electron diffraction to disentangle spin-lattice coupling of granular FePt in the time domain. The reduced dimensionality of single-crystalline FePt nano…
Femtosecond X-ray magnetic circular dichroism absorption spectroscopy at an X-ray free electron laser
Daniel J. Higley, Konstantin Hirsch, Georgi L. Dakovski +25
X-ray magnetic circular dichroism spectroscopy using an X-ray free electron laser is demonstrated with spectra over the Fe L-edges. This new ultrafast time-resolved capabil…
X-Ray Detection of Transient Magnetic Moments Induced by a Spin Current in Cu
R. Kukreja, S. Bonetti, Z. Chen +7
We have used a MHz lock-in x-ray spectro-microscopy technique to directly detect changes of magnetic moments in Cu due to spin injection from an adjacent Co layer. The elemental an…
Hot electron driven enhancement of spin-lattice coupling in 4f ferromagnets observed by femtosecond x-ray magnetic circular dichroism
Marko Wietstruk, Alexey Melnikov, Christian Stamm +7
Due to an error this article has been annouced as a new article instead of a corrected version of article 1010.1374.
Hot electron driven enhancement of spin-lattice coupling in 4f ferromagnets observed by femtosecond x-ray magnetic circular dichroism
Marko Wietstruk, Alexey Melnikov, Christian Stamm +7
Femtosecond x-ray magnetic circular dichroism was used to study the time-dependent magnetic moment of 4 fs electrons in the ferromagnets Gd and Tb, which are known for their differ…
