摘要：

Quasielastic neutron scattering experiments from La2NiO4+delta revealed a substantial hole doping effect on the 2 dimensional spin correlations. Thermal evolution of correlation length clearly shows the reduction of the exchange stiffness constant by hole doping, which is in marked contrast to that of La2CuO4+delta. The present result is reflected by the hole character in La2NiO4+delta, which is different from that in the cuprate.
