✦ Synopsis

High resolution powder neutron diffraction has been used to study the magnetic Bragg scattering in the La1.4_xPrO.6srXCu04 system.

The compositions La 1 . 4 _ X PrO. 6srXcu04 , x=o and 0.01 adopt the T'(Nd 2 Cu0 4 ) type structure with a spin structure of the Cu sublattice identical to La 2 Ni0 4 ; increased hole doping, as in La1.37PrO.6srO.03cu04' leads to a first-order structural phase transition to the
