Title: Stacked charge stripes in the quasi-2D trilayer nickelate La 4 Ni 3 O 8

Abstract

The quasi-2D nickelate La 4Ni 3O 8 (La-438), consisting of trilayer networks of square planar Ni ions, is a member of the so-called T' family, which is derived from the Ruddlesden-Popper (R-P) parent compound La 4Ni 3O 10-x by removing two oxygen atoms and rearranging the rock salt layers to fluorite-type layers. Although previous studies on polycrystalline samples have identified a 105-K phase transition with a pronounced electronic and magnetic response but weak lattice character, no consensus on the origin of this transition has been reached. We show using synchrotron X-ray diffraction on high-pO(2) floating zone-grown single crystals that this transition is associated with a real space ordering of charge into a quasi-2D charge stripe ground state. We found that the charge stripe superlattice propagation vector, q = (2/3, 0, 1), corresponds with that those in the related 1/3-hole doped single- layer R-P nickelate, La 5/3Sr 1/3NiO 4 (LSNO-1/3; Ni 2.33+), with orientation at 45 degrees to the Ni-O bonds. Furthermore, the charge stripes in La-438 are weakly correlated along c to form a staggered ABAB stacking that reduces the Coulomb repulsion among the stripes. Surprisingly, however, we find that the charge stripes within each trilayer of La-438 are stackedmore » in phase from one layer to the next, at odds with any simple Coulomb repulsion argument.« less

  • Commensurability effects for nickelates have been studied, for the first time, by neutron scattering on La{sub 5/3}Sr {sub 1/3}NiO {sub 4} . Upon cooling, this system undergoes three successive phase transitions associated with quasi-two-dimensional (2D) commensurate charge and spin stripe ordering in the NiO{sub 2} planes. The two lower temperature phases are stripe lattice states with quasi-long-range in-plane charge correlation. When the lattice of 2D charge stripes melts, it goes through an intermediate glass state before becoming a disordered liquid state. This glass state shows short-range charge order without spin order, and may be called a {open_quotes}stripe glass{close_quotes} which resemblesmore » the hexatic/nematic state in 2D melting. {copyright} {ital 1997} {ital The American Physical Society}« less
  • Layered nickelates have the potential for exotic physics similar to high T C superconducting cuprates as they have similar crystal structures and these transition metals are neighbors in the periodic table. Here we present an angle-resolved photoemission spectroscopy (ARPES) study of the trilayer nickelate La 4Ni 3O 10 revealing its electronic structure and correlations, finding strong resemblances to the cuprates as well as a few key differences. We find a large hole Fermi surface that closely resembles the Fermi surface of optimally hole-doped cuprates, including its d x2-y2 orbital character, hole filling level, and strength of electronic correlations. However, inmore » contrast to cuprates, La 4Ni 3O 10 has no pseudogap in the d x2-y2 band, while it has an extra band of principally d 3z2-r2 orbital character, which presents a low temperature energy gap. Furthermore, these aspects drive the nickelate physics, with the differences from the cuprate electronic structure potentially shedding light on the origin of superconductivity in the cuprates.« less
