Static spin correlations in lightly-doped LaCuO $_{4+delta}$

Matsuda, Masaaki; Fujita, Masaki*; Yamada, Kazuyoshi*

Neutron scattering experiments have been performed in lightly-doped LaCuO $_{4+delta}$ 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 Nel temperature is between 270 K 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.
