Abstract

Recently superconductivity wasreported by Sr intercalation in topological insulator Bi{sub 2}Se{sub 3}. In this report we extensively study anisotropic superconducting properties of Sr{sub 0.1}Bi{sub 2}Se{sub 3} with transition at ~2.9 through resistivity and DC magnetization measurement. We also discuss synthesis methodology for growth of single crystal Sr-Bi{sub 2}Se{sub 3}. The anisotropic properties of Sr{sub 0.1}Bi{sub 2}Se{sub 3} single crystals were studied using transport measurements. Using Ginzburg Landau formulas the upper critical field H{sub c2}(0) comes out to be 2.1 T and 1.4 T for magnetic field applied along the ab-plane and c-axis of the single crystalsand corresponding Ginzburg - Landau coherence lengths are ξ{sub ab} = 15.3 nm and ξ{sub c} = 10.2 nm. The sample shows weak electronic anisotropy Γ = 1.5. Hall resistivity is linear with field at 10 K.

Anisotropy in upper critical field of FeTe{sub 0.55}Se{sub 0.45}

Journal Article Shruti, ; Sharma, G. - AIP Conference Proceedings

The anisotropic properties of FeTe{sub 0.55}Se{sub 0.45} single crystals are studied using transport measurements. FeTe{sub 0.55}Se{sub 0.45} shows onset superconducting transition at 14.2 K. The data measured on single crystals give a high upper critical field H{sub c2}(0) equal to 93.95 T and 67.32 T for magnetic field applied perpendicular and parallel to c axis of the sample respectively. Corresponding electronic anisotropy is estimated to be γ∼1.4 and Ginzburg-Landau coherence lengths are ξ{sub ab}=22.12 Å and ξ{sub c}=15.8 Å. Temperature and field dependent specific heat data are also reported.

Quasi-two-dimensional fluctuations in the magnetization of $L a_{1.9} C a_{1.1} C u_{2} O_{6 + δ}$ superconductors

Journal Article Shi, Xiaoya; Dimitrov, I.; Ozaki, Toshinori; ... - Physical Review B

We report the results of magnetization measurements with the magnetic field applied along the c axis on superconducting La_1.9Ca_1.1Cu₂O_6+δ single crystals processed under ultrahigh oxygen pressure. Strong fluctuation effects were found in both low- and high-field regimes. Scaling analysis of the high-field magnetization data near the critical temperature (T_c = 53.5K) region reveals the characteristics of critical fluctuation behavior of quasi-two-dimensional (2D) superconductivity, described by Ginzburg-Landau theory using the lowest Landau level approximation. Low-field magnetic susceptibility data can be successfully explained by the Lawrence-Doniach model for a quasi-2D superconductor, from which we obtained the a b plane Ginzburg-Landau coherence lengthmore »« less

Quantum oscillations in strong magnetic fields, berry phase, and superconductivity in three-dimensional topological Bi{sub 2–x}Cu{sub x}Se{sub 3} insulators

Journal Article Knyazev, D.; Prudkoglyad, V.; Romanova, T.; ... - Journal of Experimental and Theoretical Physics

Two-dimensional (2D) Shubnikov–de Haas oscillations and 2D Hall oscillations are observed in 3D copper-doped Bi{sub 2}Se{sub 3} single crystals in magnetic fields up to 19.5 T at temperatures down to 0.3 K. Three samples with a high bulk carrier concentration (n ≈ 10{sup 19}–10{sup 20} cm{sup –3}) are studied. The rotation of the samples in a magnetic field shows that these oscillations are related to numerous parallel 2D conducting channels 1–5 nm thick. Their basic kinetic parameters are found. Quantized Hall resistance R{sub xy} is detected in 1-nm-thick 2D conducting channels at high fields. The distance Δ(1/R{sub xy}) between themore »« less

Upper critical field of a Sm sub 1. 85 Ce sub 0. 15 CuO sub 4 minus y single crystal: Interaction between superconductivity and antiferromagnetic order in copper oxides

Journal Article Dalichaouch, Y; Lee, B; Seaman, C; ... - Physical Review Letters; (USA)

The temperature dependence of the anisotropic upper critical magnetic field, {ital H}{sub {ital c}2}(T), has been determined resistively in antiferromagnetic Sm{sub 1.85}Ce{sub 0.15}CuO{sub 4{minus}{ital y}} single crystals. We observe the first evidence in high-{ital T}{sub {ital c}} copper oxides for the interaction between superconductivity and antiferromagnetic ordering of rare-earth ions; estimates of the exchange coupling {ital J}{approx}0.1 eV and the Ginzburg-Landau coherence lengths {xi}{sub {ital ab}}=79 A and {xi}{sub {ital c}}=14.7 A are obtained. In both Nd{sub 1.84}Ce{sub 0.16}CuO{sub 4{minus}{ital y}} and Sm{sub 1.85}Ce{sub 0.15}CuO{sub 4{minus}{ital y}}, the {ital H}{sub {ital c}2} data above {ital T}{sub {ital N}} can bemore »« less

Studies of anisotropy of iron based superconductors

Thesis/Dissertation Murphy, Jason

To study the electronic anisotropy in iron based superconductors, the temperature dependent London penetration depth, Δλ (T), have been measured in several compounds, along with the angular dependent upper critical field, H_c2(T). Study was undertaken on single crystals of Ba(Fe_1-xCo_x)₂As₂ with x=0.108 and x=0.127, in the overdoped range of the doping phase diagram, characterized by notable modulation of the superconducting gap. Heavy ion irradiation with matching field doses of 6 T and 6.5 T respectively, were used to create columnar defects and to study their effect on the temperature Δλ (T). The variation of the low-temperature penetration depth in bothmore »« less
