“…They found that the system of Y 1−x Ca x Ba 2 Cu 3 O 6+δ is a very suitable system for studying the variation of charge carrier density, since it allows one to directly control the oxygen content in the system. 11 Based on the experimental results, we believe that the T * is related to the Ca-doping level.…”

The understanding of the spin gap phenomenon in the normal state of the high temperature superconductors can provide the mechanism of the high temperature superconductivity. A specific function of thermal excitation for quasiparticles was introduced based on the experimental relationship between resistivity and temperature. This specific function describes the deviation in resistivity from the T -linear relationship w.r.t. the normal state of the high temperature superconductors. With this function, the spin gap is naturally introduced. Our experimental results indicate that the spin gap behavior is closely related not only to the oxygen deficiency but also to the structural change in the a-b plane. Furthermore, we found that the crossover from anomalous metallic state to spin gap state takes place within a temperature range T S < T < T * , which depends on the oxygen content and the Ca-doping level. Pressure effects on the spin gap phenomenon in bulk samples of oxygen-deficient YBa 2 Cu 3 O 6+δ and Ca-doped Y 1−x CaxBa 2 Cu 3 O 6+δ were also investigated. Under high hydrostatic pressure the spin gap behavior is also severely influenced by the contraction of the a-b plane due to the pressure. Int. J. Mod. Phys. B 1999.13:3219-3234.
