Scientists used spiraling x-rays at the ALS to observe, for the first time, a property that gives handedness to swirling electric patterns—dubbed polar vortices—in a synthetically layered material. Read more »
How to Directly Probe ac Spin Currents
Scientists working at the ALS have made the first unambiguous, direct measurements of ac spin currents flowing through nanostructured metal layers. The work represents a crucial step toward the development of future spintronic devices that are smaller, faster, and more energy efficient. Read more »
