Mott insulator to correlated metal: Optical study of La1-xTiO3
Abstract
The room-temperature reflectance of a well-characterized series of samples (x-ray, neutron activation and thermigravimetric analyses, resistivity, magnetization) in the La1-xTiO3 system has been measured between 50 and 40 000 cm-1 on samples ranging from the antiferromagnetic insulating (LaTiO3) to the metallic (La0.88TiO3) part of the phase diagram. The electronic portion of the low-frequency optical conductivity increases with frequency at …
