Coupled Charge-Spin Correlations in the Pyrochlore Tl2Mn2O7 Probed by Ultrafast Mid-Infrared Spectroscopy

Abstract

An optical-pump, mid-infrared (IR)-probe system is used to investigate ultrafast temperature-dependent dynamics in the magnetoresistive pyrochlore Tl2Mn2O7. We observe a prolonged carrier density increase, related to a scaling of the carrier lifetime with spin correlations.
