Title: Local lattice distortions and dynamics in extremely overdoped superconducting YSr ₂ Cu _2.75 Mo _0.25 O _7.54

Abstract

A common characteristic of many “overdoped” cuprates prepared with high-pressure oxygen isT_cvalues ≥ 50 K that often exceed that of optimally doped parent compounds, despite O stoichiometries that place the materials at the edge or outside of the conventional boundary between superconducting and normal Fermi liquid states. X-ray absorption fine-structure (XAFS) measurements at 52 K on samples of high-pressure oxygen (HPO) YSr₂Cu_2.75Mo_0.25O_7.54,T_c= 84 K show that the Mo is in the (VI) valence in an unusually undistorted octahedral geometry with predominantly Mo neighbors that is consistent with its assigned substitution for Cu in the chain sites of the structure. Perturbations of the Cu environments are minimal, although the Cu X-ray absorption near-edge structure (XANES) differs from that in other cuprates. The primary deviation from the crystal structure is therefore nanophase separation into Mo- and Cu-enriched domains. There are, however, indications that the dynamical attributes of the structure are altered relative to YBa₂Cu₃O₇, including a shift of the Cu-apical O two-site distribution from the chain to the plane Cu sites. Another effect that would influenceT_cis the possibility of multiple bands at the Fermi surface caused by the presence of the second phase and the lowering of the Fermi level.

Local structure of Sr ₂ CuO _3.3 , a 95 K cuprate superconductor without CuO ₂ planes

Journal Article Conradson, Steven D. ; Geballe, Theodore H. ; Jin, Changqing ; ... - Proceedings of the National Academy of Sciences of the United States of America

The local structure of the highly “overdoped” 95 K superconductor Sr ₂ CuO _3.3 determined by Cu K X-ray absorption fine structure (XAFS) at 62 K in magnetically oriented samples shows that 1) the magnetization is perpendicular to the c axis; 2) at these levels of precision the Cu sublattice is tetragonal in agreement with the crystal structure; the O sublattice has 3) continuous -Cu-O- chains that orient perpendicular to an applied magnetic field; 4) approximately half-filled -Cu-O- chains that orient parallel to this field; 5) a substantial number of apical O vacancies; 6) O ions at some apical positionsmore »« less

Nonadiabatic coupling of the dynamical structure to the superconductivity in YSr₂Cu_2.75Mo_0.25O_7.54 and Sr₂CuO_3.3

Journal Article Conradson, Steven D. ; Geballe, Theodore H. ; Jin, Chang-Qing ; ... - Proceedings of the National Academy of Sciences of the United States of America

A crucial issue in cuprates is the extent and mechanism of the coupling of the lattice to the electrons and the superconductivity. Here we report Cu K edge extended X-ray absorption fine structure measurements elucidating the internal quantum tunneling polaron (iqtp) component of the dynamical structure in two heavily overdoped superconducting cuprate compounds, tetragonal YSr₂Cu_2.75Mo_0.25O_7.54 with superconducting critical temperature, T_c = 84 K and hole density p = 0.3 to 0.5 per planar Cu, and the tetragonal phase of Sr₂CuO_3.3 with T_c = 95 K and p = 0.6. In YSr₂Cu_2.75Mo_0.25O_7.54 changes in the Cu-apical O two-site distribution reflect amore »« less

Evolution of Charge-Lattice Dynamics across the Kuramoto Synchronization Phase Diagram of Quantum Tunneling Polarons in Cuprate Superconductors

Journal Article Velasco, Victor ; Silva Neto, Marcello B. ; Perali, Andrea ; ... - Condensed Matter

Because of its sensitivity to the instantaneous structure factor, S(Q,t = 0), Extended X-ray Absorption Fine Structure (EXAFS) is a powerful tool for probing the dynamic structure of condensed matter systems in which the charge and lattice dynamics are coupled. When applied to hole-doped cuprate superconductors, EXAFS has revealed the presence of internal quantum tunneling polarons (IQTPs). An IQTP arises in EXAFS as a two-site distribution for certain Cu–O pairs, which is also duplicated in inelastic scattering but not observed in standard diffraction measurements. The Cu–Sr pair distribution has been found to be highly anharmonic and strongly correlated to bothmore »« less

Crystal structure of the high-T{sub c} superconductor HoSr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7.54} by joint time-of-flight neutron/x-ray rietveld refinement

Journal Article Harrison, W T.A. ; Roliard, S ; Jacobson, A J - Journal of Solid State Chemistry

The ambient-pressure synthesis, crystal structure, and some properties of HoSr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7.54} are described. HoSr{sub 2} Cu{sub 2.7}Mo{sub 0.3}O{sub 7.54} crystallizes as the tetragonal modification of the YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (123) high-T{sub c} superconductor structure, and exhibits a superconducting transition temperature of {approximately}30 K. The Cu/Mo cation distribution in HoSr{sub 2}Cu{sub 2.7}Mo{sub 0.3O}{sub 7.54} was established by means of a joint time-of-flight neutron/X-ray Rietveld refinement: The molybdenum ions substitute for copper at both the {open_quotes}chain{close_quotes} [Cu(1)] and square-pyramidal [Cu(2)] sites in roughly equal proportion. The chain layers [atoms Cu/Mo(1) and O(1)] show considerable static disorder in thismore »« less

Crystal structure and superconductivity of the Mo-stabilized Sr-based YSr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7-{delta}} compound

Journal Article Hu, S F ; Jefferson, D A ; Liu, R S ; ... - Journal of Solid State Chemistry

The crystal structure of the Mo-stabilized Sr-based superconductor with nominal composition YSr{sub 2}Cu{sub 2.7}Mo{sub 0.3}O{sub 7-{delta}} has been analyzed by X-ray powder diffraction (XRD), electron diffraction, and high-resolution electron microscope techniques. The material crystallizes in the space group P4/mmm, with lattice parameters a = 3.8138(2) and c = 11.5204(8) {angstrom}. In the structure, the Mo ions are exclusively substituted for copper and are located mainly on the planar coordinated [Cu(2)] sites ({approximately}24%), with only a small proportion on the chain [Cu(1)] sites ({approximately} 6%) in the parent YBa{sub 2}Cu{sub 3}O{sub 7}(123-type) structure.
