Here we show experimental evidence for an alternative type of in-plane exchange-bias effect present at room temperature that is created from a chiral 90∘ domain wall at the interface of a ferrimagnetic-ferromagnetic $\mathrm{Dy-Co/Ni-Fe}$ bilayer system [...] OpenAccess: PDF PDF (PDFA); 2019-08-2915:37 [PUBDB-2019-03147] Journal Article et al Direct Visualization of Spatial Inhomogeneity of Spin Stripes Order in $\mathrm{La_{1.72}Sr_{0.28}NiO_{4}}$ Condensed Matter 4(3), 77 (2019) [10.3390/condmat4030077]   In several strongly correlated electron systems, the short range ordering of defects, charge and local lattice distortions are found to show complex inhomogeneous spatial distributions. There is growing evidence that such inhomogeneity plays a fundamental role in unique functionality of quantum complex materials [...] OpenAccess: PDF PDF (PDFA); 2019-08-2520:30 [PUBDB-2019-03101] Journal Article et al Anomalous Dynamics of Concentrated Silica-PNIPAm Nanogels The journal of physical chemistry letters 10, 5231 - 5236 (2019) [10.1021/acs.jpclett.9b01690]   We present the structure and dynamics of highly concentrated core–shell nanoparticles composed of a silica core and a poly(N-isoproylacrylamide) (PNIPAm) shell suspended in water. With X-ray photon correlation spectroscopy, we are able to follow dynamical changes over the volume phase transition of PNIPAm at LCST = 32 °C. [...] Published on 2019-08-21.

The local structure of this model system is dominated by four- and sixfold order.

The device is capable of splitting a single X-ray pulse into two fractions to introduce time delays from −5 to 815 ps with femtosecond resolution [...] OpenAccess: PDF PDF (PDFA); 2019-04-1713:27 [PUBDB-2019-02010] Journal Article et al Monitoring Nanocrystal Self-Assembly in Real Time Using In Situ Small-Angle X-Ray Scattering Small 15(20), 1900438 (2019) [10.1002/smll.201900438]   Self‐assembled nanocrystal superlattices have attracted large scientific attention due to their potential technological applications. However, the nucleation and growth mechanisms of superlattice assemblies remain largely unresolved due to experimental difficulties to monitor intermediate states. [...] Published on 2019-04-16.

The XFELO complements existing sources based on self-amplified spontaneous emission (SASE) from high-gain X-ray free-electron lasers (XFEL) that produce ultra-short pulses with broad-band chaotic spectra [...] OpenAccess: PDF PDF (PDFA); 2019-03-2214:32 [PUBDB-2019-01681] Journal Article et al Spatial and temporal pre-alignment of an X-ray split-and-delay unit by laser light interferometry Review of scientific instruments 90(4), 045106 (2019) [10.1063/1.5089496]   We present a novel experimental setup for performing a precise pre-alignment of a hard X-ray split-and-delay unit based on low coherence light interferometry and high-precision penta-prisms. A split-and-delay unit is a sophisticated perfect crystal-optics device that splits an incoming X-ray pulse into two sub-pulses and generates a controlled time-delay between them.
