La{sub 2}NiO{sub 4} is a Mott-Hubbard insulator consisting of antiferromagnetic NiO{sub 2} planes alternating with La{sub 2}O{sub 2} layers. The NiO{sub 2} planes can be doped with holes. There is now considerable evidence that the insulating behavior occurs because the dopant-induced holes tend to order themselves in periodically spaced stripes. The authors present a detailed neutron scattering study of the ordering of spins and holes in oxygen doped La{sub 2}NiO{sub 4.133}. The temperature dependence of the stripe spacing, the width of the stripes and the extent of their pinning to the lattice are investigated.
