The electronic structure change induced by stripe phase formation in cuprates

Abstract

It has been suggested that the stripe phase shows ID charge transport in the CuO2 planes instead of the 2D characteristics of the Zhang-Rice band. X-ray absorption near edge spectroscopy (XANES) has been used to study the electronic structure of the stripe phase compounds La2-xSrxCuO4, and La2-x-yNdySrxCuO4 for x around 1/8. The measurements were performed at both 300 and 28 K to examine the possible electronic structure change above and below the temperature of the stripe phase formation. (C) 2004 Elsevier B.V.
