Abstract

High resolution powder neutron diffraction has been used to study the magnetic Bragg scattering in the La_1.4-xPr_0.6Sr_xCuO₄ system. The compositions La_1.4-xPr_0.6Sr_xCuO₄, 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 La_1.37Pr_0.6Sr_0.03CuO₄, leads to a first-order structural phase transition to the 0 (K₂NiF₄) type structure and destroys the Néel state.
