On Ultrafast X-ray Methods for Magnetism
Rajan Plumley, Sathya Chitturi, Cheng Peng +36
With the introduction of x-ray free electron laser sources around the world, new scientific approaches for visualizing matter at fundamental length and time-scales have become poss…
Antiferromagnetic real-space configuration probed by dichroism in scattered x-ray beams with orbital angular momentum
Margaret R. McCarter, Ahmad I. U. Saleheen, Arnab Singh +8
X-ray beams with orbital angular momentum (OAM) are a promising tool for x-ray characterization techniques. Beams with OAM have a helicity--an azimuthally varying phase--which lead…
Nanoscale inhomogeneity of charge density waves dynamics in LaSrNiO
Gaetano Campi, Antonio Bianconi, Boby Joseph +7
While stripe phases with broken rotational symmetry of charge density appear in many complex correlated systems, the heterogeneity of spatial ordering and dynamics remains elusive.…
Simultaneous ambient pressure X-ray photoelectron spectroscopy and grazing incidence X-ray scattering in gas environments
H. Kersell, P. Chen, H. Martins +9
We have developed an experimental system to simultaneously observe surface structure, morphology, composition, chemical state, and chemical activity for samples in gas phase enviro…
Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice
Justin Woods, Xiaoqian M Chen, Rajesh V. Chopdekar +12
Artificial spin ices (ASI) have been widely investigated as magnetic metamaterials with exotic properties governed by their geometries. In parallel, interest in X-ray photon orbita…
Direct measurement of temporal correlations above the spin-glass transition by coherent resonant magnetic x-ray spectroscopy
Jingjin Song, Sheena K. K. Patel, Rupak Bhattacharya +9
In the 1970s a new paradigm was introduced that interacting quenched systems, such as a spin-glass, have a phase transition in which long time memory of spatial patterns is realize…
Measurement of spin dynamics in a layered nickelate using x-ray photon correlation spectroscopy: Evidence for intrinsic destabilization of incommensurate stripes at low temperatures
Alessandro Ricci, Nicola Poccia, Gaetano Campi +15
We study the temporal stability of stripe-type spin order in a layered nickelate with X-ray photon correlation spectroscopy and observe fluctuations on time scales of tens of minut…
Direct Visualization of Spatial inhomogeneity of Spin Stripes Order in La1.72Sr0.28NiO4
Gaetano Campi, Nicola Poccia, Boby Joseph +14
In several strongly correlated electron systems, defects, charge and local lattice distortions are found to show complex inhomogeneous spatial distributions. There is growing evide…
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…
Temperature dependence of in-plane correlation lengths in exchange biased Co/FeF2
X. Lu, S. Roy, E. Blackburn +4
We have measured resonant soft x-ray diffuse magnetic scattering as a function of temperature in a positively exchange biased Co/FeF2 bilayer and analyzed the data in the distorted…
