Transient Exchange Interaction in a Helical Antiferromagnet
M. C. Langner, S. Roy, A. F. Kemper +8
We have performed time-resolved resonant x-ray scattering studies in the Lanthanide metal Dy to reveal the dynamic response of the helical order exchange coupling to injection of u…
Glass-like recovery of antiferromagnetic spin ordering and dimensional crossover in a photo-excited manganite PrCaMnO
S. Y. Zhou, M. C. Langner, Y. Zhu +10
Electronic orderings of charges, orbitals and spins are observed in many strongly correlated electron materials, and revealing their dynamics is a critical step toward understandin…
Ferromagnetic Enhancement of CE-type Spin Ordering in (Pr,Ca)MnO
S. Y. Zhou, Y. Zhu, M. C. Langner +12
We present resonant soft X-ray scattering (RSXS) results from small band width manganites (Pr,Ca)MnO, which show that the CE-type spin ordering (SO) at the phase boundary is st…
Band-selective Measurement of Electronic Dynamics in VO2 using Femtosecond Near Edge X-ray Absorption
A. Cavalleri, M. Rini, H. H. W. Chong +5
We report on the first demonstration of femtosecond xray absorption spectroscopy. Our experiments are made possible by the use of broadly tunable bending-magnet radiation from lase…
Evidence for a Structurally-driven Insulator-to-metal Transition in VO2: a View from the Ultrafast Timescale
A. Cavalleri, Th. Dekorsy, H. H. Chong +2
We apply ultrafast spectroscopy to establish a time-domain hierarchy between structural and electronic effects in a strongly-correlated electron system. We discuss the case of the…
