Abstract

In this paper we report the first observation of stripe correlations of holes in hole-doped La₂NiO₄ by X-ray diffraction. The experiment was performed in Laue geometry at the hard X-ray beamline BW5 at HASYLAB on a crystal of La_1.775Sr_0.225NiO₄ previously studied by neutron diffraction. Temperature dependences of the intensities and wave vectors of the charge-density-modulation peaks were characterized and found to be in good agreement with the neutron scattering results. Interestingly, weak, temperature-dependent scattering was also observed at positions consistent with nonresonant X-ray magnetic scattering from the spin correlations; however, a definitive determination of its origin remains lacking.
