Ultrafast Dynamics in Magnetoresistance Manganites: Vibrationally-driven Transitions and X-ray Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

We report studies of ultrafast insulator-metal transitions in manganites by selective vibrational excitation of the Mn-O stretch and above-gap excitation. Time-resolved x-ray spectroscopy probes changes in O-2p and Mn-3d electronic states near the Fermi level.
