Berkeley Lab
The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

Electrical Switching of Magnetic Vortex Circulation

Photoemission electron microscopy (PEEM) experiments have demonstrated that the circulation direction of a magnetic vortex can be switched by the application of an electric field, opening the door to digital devices with more streamlined system designs, improved performance, and greater energy efficiency. ...

Berkeley Lab and SLAC Host Hard X-Ray Photoemission Conference

Earlier this month, Berkeley Lab and SLAC hosted the 7th International Conference on Hard X-Ray Photoelectron Spectroscopy (HAXPES). This biennial meeting has grown from a small workshop held at ESRF in 2003 with about 50 participants, to a truly international event, which this year attracted 150 participants from 20 countries. ...

The Mystery of the Lightweight Electrons

Copper oxides are important for superconductivity applications but are difficult to understand due to complex charge, spin, and orbital interactions. Now, studies at the ALS have found such a system in which observations of effective electron mass are at odds with state-of-the-art electronic-structure calculations. ... Read more »
