A team including SLAC researchers has measured the intricate interactions between atomic nuclei and electrons that are key to understanding intriguing materials properties, such as high-temperature superconductivity.

Combining X-ray and electron data from two cutting-edge SLAC instruments, researchers make the first observation of the rapid atomic response of iron-platinum nanoparticles to light. The results could help develop ways to manipulate and control future magnetic data storage devices.

In experiments with the lab’s ultrafast "electron camera," laser light hitting a material is almost completely converted into nuclear vibrations, which are key to switching a material’s properties on and off for future electronics and other applications.

A new device could open new avenues for the generation of high-frequency radiation with applications in science, radar, communications, security and medical imaging.
