Abstract

Charge and spin ordering in La2NiO4.17 has been studied by 139La NMR using the field and temperature dependence of the linewidth and relaxation rates. The stripes are site centered and the domain spins freeze at ~ 180 K, followed by a second transition at ~ 50 K, where the spins on the domain walls freeze. Although consistent with the neutron measurements, the results are quantitatively different from the NMR results in a nickelate with quenched Sr disorder.
