High resolution powder neutron diffraction has been used to study the magnetic Bragg scattering in the La1.4-xPr0.6SrxCuO4 system. The compositions La1.4-xPr0.6SrxCuO4, x=0 and 0.01 adopt the T1(Nd2CuO4) type structure with a spin structure of the Cu sublattice identical to La2NiO4; increased hole doping, as in La1.37Pr0.6Sr0.03CuO4, leads to a first-order structural phase transition to the 0 (K2NiF4) type structure and destroys the Néel state.
