The temperature and doping dependence of the 2D Hubbard model is studied in the intermediate coupling regime U 4: Strong 2D critical spin fluctuations dominating near half-filling are completely destroyed upon about 14% doping concentration, below which the imaginary part of the self-energy vanishes
The magnetic properties of the Ndl ,Sr,CuO 1 R system are studied by powder neutron diffraction. Formally reduced samples (X s 0.06) show similar magnetic behaviour to undoped Nd,CuO,, while in formally oxidised ones (0.1 s x c 0.2) the long range Cu antiferromagnetic order is rapidly destroyed upon
