Abstract

Neutron scattering experiments have revealed a fascinating interplay between the hole doping, the spin fluctuations, and the superconductivity of the cuprate superconductors. Recently, electrochemical techniques have been used to produce large single crystals of La 2 CuO 4+ y , which has mobile oxygen dopants. Staging behavior of the excess oxygen has been demonstrated, and the low-energy spin fluctuations in stage 6 La 2 CuO 4+ y have been measured. The spin fluctuations are incommensurate with the lattice and have spatial, energy, and temperature dependencies very much like those in La 2− x Sr x CuO 4 , with similar high transition temperature. This establishes the universality of the incommensurate spin fluctuations among the La 2 CuO 4 -based superconductors.
