Femtosecond optical lasers can be used to trigger drastic modifications of a material’s physical properties on the ultrafast timescale, revealing complex, otherwise inaccessible quantum mechanics as well as new processes with potential for creating novel devices with unprecedented high performance. Here, the authors report that the interaction of near-infrared laser light with a promising spin-orbitronics candidate, the layered mixed-valence manganite NdSrMnO, produces unexpected results, triggering dramatic modifications in the spin state of the material while leaving its orbital state unperturbed. These observations are made with an x-ray free-electron laser, while optical spectroscopy further reveals the specific way electrons transfer within the system. The results open an opportunity to selectively control the spin state while keeping the orbital one intact, an extremely challenging task in strongly correlated electron systems. They pave an avenue for the next generation of multistate logic and memory devices.
