Remote Operation of the PEEM Endstation

We have recently upgraded the PEEM endstation at the SIM beamline to enable remotely controlled experiments via internet and mailed-in samples. Sample positioning and tilt control is now possible by means of a motorized sample stage. A newly developed computer controlled switchbox is available for remote temperature control and in situ application of electric or magnetic fields to the sample.

Novel optics enable better X-ray Free Electron Laser experiments

Our research on multifocus off-axis zone plates was accepted in “Optica”, the highest impact journal of the Optical Society of America. In the paper we report on different ways to combine focusing and beam-splitting functionalities in one single optical element.

Microwave excitation leads to a magnetic cascade

Magnon Modes of Microstates and Microwave-Induced Avalanche in Kagome Artificial Spin Ice with Topological Defects

In this work the spin dynamics of microstates in artificial spin ice (ASI) in Ni81Fe19 nanomagnets arranged in an interconnected kagome lattice has been investigated using microfocus Brillouin light scattering, broadband ferromagnetic resonance, magnetic force microscopy, x-ray photoemission electron microscopy, and micromagnetic simulations. The findings are key for the creation of avalanches inside the kagome ASI and reprogrammable magnonics based on ASIs.

(a) Scanning transmission x-ray microscopy images of magnetic skyrmions stabilized in a nanostructured Pt/Co/Ir disc; (b) Skyrmion-dependent contribution to the Hall resistivity

Discrete Hall contribution of magnetic skyrmions

The reliable electrical detection of magnetic skyrmions is of fundamental importance for the application of such topological magnetic quasi-particles for data storage devices. Researchers in a joint collaboration between the University of Leeds and the PolLux endstation have investigated the electrical detection of isolated magnetic skyrmions in applications-relevant nanostructured devices, observing the presence of a strong skyrmion-dependent contribution to the Hall resistivity.

Atmosphere in X-ray light

Media Releases Energy and Environment Research Using Synchrotron Light Enviroment

PSI researchers have developed an experimental chamber in which they can recreate atmospheric processes and probe them with unprecedented precision, using X-ray light from the Swiss Light Source SLS. In the initial experiments, they have studied the production of bromine, which plays an essential role in the decomposition of ozone in the lower layers of the atmosphere. In the future, the new experiment chamber will also be available for use by researchers from other scientific fields.
