Dependence of the pseudogap parameter on the wave vector in high-temperature superconductors

Abstract

The possibilities of obtaining information on the pseudogap parameter dependence on the wave vector in high-temperature superconductors based on layered cuprates by analyzing the temperature behavior of the line shift of the nuclear quadrupole resonance (NQR) on the Cu and O nuclei are discussed. As an example, the Cu NQR data available for YBa2Cu4O 8 are analyzed. © 2008 Pleiades Publishing, Ltd.
