Time-resolved X-ray Absorption Spectroscopy of Photoindueed Insulator-Metal Transition in a Colossal Magnetoresistive Manganite

摘要

We studied the ultrafast insulator-metal transition in a manganite by means of picosecond X-ray absorption at the O K- and Mn L-edges, probing photoindueed changes in O-2p and Mn-3d electronic states near the Fermi level.
