Neutron scattering experiments have been performed in lightly-doped La 2CuO4+δ in order to study coexistence of a three-dimensional antiferromagnetic (AF) long-range ordered phase and a spin-glass (SG) phase in a very lightly-doped region. Although we studied in a limited range of hole concentration, where Néel temperature is between 270 and 320 K, no sign of the SG phase was observed, suggesting that there may exist a threshold to realize the phase separation into the AF and SG phases.
