Dance of the Nanovortices

Last udpate: 12/23/2015 9:55:38 AM

The trajectories of small magnetic entities referred to as skyrmions have been captured and recorded with the help of X-ray holography. Researchers gained new insight from the analysis of this motion: these nanoscale vortices possess mass. The discovery is published in Nature Physics 2 February 2015. read more

Nanosolvation of a protonated peptide dimer in the gas phase

Last udpate: 2/27/2015 7:16:10 PM

The structure and functionality of biomolecules are intrinsically linked with the aqueous environment dominating in vivo. In particular, scientists are aiming at understanding the effect of the surrounding water solvation shell on the conformation and stability of these species. read more

High-resolution films of chemical reactions

Last udpate: 2/27/2015 7:09:14 PM

X-ray free-electron lasers (XFELs) will bring motion into the understanding of chemical reactivity. This will open the door to the development of new products and more efficient chemical production processes. At present, what is observed in chemical reactions is a sudden change from reactants to products. In future research, X-ray flashes of unprecedented brightness and extremely short pulse durations will permit the recording of molecular films with an incredible level of detail. It will become possible to understand the elementary steps taking place inside molecules long before chemical reactions are completed. read more

Insight into inner magnetic layers

Last udpate: 2/18/2015 10:01:00 AM

Measurements at BESSY II have shown how spin filters forming within magnetic sandwiches influence tunnel magnetoresistance – results that can help in designing spintronic components. Research teams from Paris, Madrid and Berlin have observed for the first time how magnetic domains mutually influence one another at interfaces of spintronic components. Using measurements taken at BESSY II, they could demonstrate that what are known as spin filters form between the outer ferromagnetic layers and the inner anti-ferromagnetic insulating layer, influencing tunnel magnetoresistance (TMR). In doing so, the teams enhanced our understanding of processes that are important for future TMR data storage devices and other spintronic components. Their results have now been published in Nature Communications. read more

Messages from Space

Last udpate: 2/11/2015 1:49:46 PM

Geologists from the University of Cambridge uncover hidden magnetic messages from the early solar system in meteorites measured at BESSY II. The team of scientists led by Dr. Richard Harrison has captured information stored inside tiny magnetic regions in meteorite samples using the PEEM-Beamline at BESSY II. This information captures the dying moments of the magnetic field during core solidification on a meteorite parent body, providing a sneak preview of the fate of Earth’s own magnetic field as its core continues to freeze. read more

Beyond the Great Wall: Gold of the Silk Roads and the First Empire of the Steppes

Last udpate: 6/12/2014 10:59:12 AM

Defining the trade routes of ancient civilizations is of particular importance when no written sources are available. The fragility, rarity, and preciousness of ancient gold work require the use of nondestructive techniques like X-ray fluorescene at BAMline at BESSY II. read more
