Title: Vortex phases and glassy dynamics in the highly anisotropic superconductor HgBa₂CuO_4+δ

Abstract

We present an extensive study of vortex dynamics in a high-quality single crystal of HgBa2CuO4+delta, a highly anisotropic superconductor that is a model system for studying the effects of anisotropy. From magnetization M measurements over a wide range of temperatures T and fields H, we construct a detailed vortex phase diagram. We find that the temperature-dependent vortex penetration field H-p(T), second magnetization peak H-smp(T), and irreversibility field H-irr(T) all decay exponentially at low temperatures and exhibit an abrupt change in behavior at high temperatures T/T-c > similar to 0.5. By measuring the rates of thermally activated vortex motion (creep) S(T, H) = vertical bar dInM(T, H)/dInt vertical bar, we reveal glassy behavior involving collective creep of bundles of 2D pancake vortices as well as temperature- and time tuned crossovers from elastic (collective) dynamics to plastic flow. Based on the creep results, we show that the second magnetization peak coincides with the elastic-to-plastic crossover at low T, yet the mechanism changes at higher temperatures.

The penetration field, {ital H}{sub {ital p}}, the width of the magnetization loops, {Delta}{ital M}, and the irreversibility field, {ital H}{sub irr}, of each compound were found to exhibit an exponential temperature dependence [i.e., {ital H}{sub {ital p}}, {ital H}{sub irr}, {Delta}{ital M}{proportional_to}exp({minus}{ital cT}/{ital T}{sub 0})]. This suggests that their magnetic relaxation is controlled by the penetration of two-dimensional pancake vortices over the Bean-Livingston surface barrier.

Synchrotron x-ray scattering study of charge-density-wave order in ${HgBa}_{2} {CuO}_{4 + δ}$

Journal Article Tabis, W. ; Yu, B. ; Bialo, I. ; ... - Physical Review B

We present a detailed synchrotron x-ray scattering study of the charge-density-wave (CDW) order in simple tetragonal HgBa2CuO4+delta (Hg1201). Resonant soft x-ray scattering measurements reveal that short-range order appears at a temperature that is distinctly lower than the pseudogap temperature and in excellent agreement with a prior transient reflectivity result. Despite considerable structural differences between Hg1201 and YBa2Cu3O6+delta, the CDWcorrelations exhibit similar doping dependencies, and we demonstrate a universal relationship between the CDWwave vector and the size of the reconstructed Fermi pocket observed in quantum oscillation experiments. The CDWcorrelations in Hg1201 vanish already below optimal doping, once the correlation length ismore »« less

Using measurements of the magnetization hysteresis we determine the temperature and field dependence of the critical current density, the pinning force and the irreversibility lines of polycrystalline HgBa{sub 2}CuO{sub 4+{delta}}, HgBa{sub 2}CaCu{sub 2}O{sub 6+{delta}} and HgBa{sub 2}Ca{sub 2}Cu{sub 3}O{sub 8+{delta}}. For all three materials we observe an exponential decay of the critical current with increasing temperature and/or field. The temperature dependence of the irreversibility fields follows a power law, H{sub irr}{approx}(1-T/{Tc}){sup 4}, and is intermediate to that of YBa{sub 2}Cu{sub 3}O{sub 7} and the Bi/Tl-based superconductors. These results are analyzed in a model in which the separation between the superconductingmore »« less

Phonon spectrum of underdoped HgBa₂CuO_4+δ investigated by neutron scattering

Journal Article Ahmadova, I. ; Sterling, T. C. ; Sokolik, A. C. ; ... - Physical Review B

The cuprates exhibit a prominent charge-density-wave (CDW) instability with a wave vector along [100], i.e., the Cu-O bond direction. Whereas CDW order is most prominent at moderate doping and low temperature, there exists increasing evidence for dynamic charge correlations throughout a large portion of the temperature-doping phase diagram. In particular, the signatures of incipient charge order have been observed as phonon softening and/or broadening near the CDW wave vector approximately halfway through the Brillouin zone. Most of this work is focused on moderately doped cuprates, for which the CDW order is robust, or on optimally doped samples, for which themore »« less
