Abstract
139La NQR spectra and relaxation measurements in the La2-xSrxCuO4 (LSCO) system are presented for x or=0.02 the long-range AF order is totally suppressed. For 0.02 200 K a relaxation contribution due to excess O, and this phenomenon is related to phase separation which leads to a superconducting phase for appropriate O doping of La2CuO4.
