Title: Critical current density and mechanism of vortex pinning in K_xFe_2-ySe₂ doped with S

Abstract

We report the critical current density J_c in K_xFe_2-ySe_2-zS_z crystals. The J_c can be enhanced significantly with optimal S doping (z=0.99). For K_0.70(7)Fe_1.55(7)Se_1.01(2)S_0.99(2), the weak fishtail effect is found for H II c. The normalized vortex pinning forces follow the scaling law with a maximum position at 0.41 of the reduced magnetic field. These results demonstrate that the small size normal point defects dominate the vortex pinning mechanism.

Giant increase of critical current density and vortex pinning in Mn doped K{sub x}Fe{sub 2−y}Se{sub 2} single crystals

Journal Article Li, Mingtao ; Zhang, Jincang ; Materials Genome Institute, Shanghai University, Shanghai 200444 ; ... - Applied Physics Letters

We report a comparative study of the critical current density (J{sub c}) and vortex pinning among pure and Mn doped K{sub x}Fe{sub 2−y}Se{sub 2} single crystals. It is found that the J{sub c} values can be greatly improved by Mn doping and post-quenching treatment when comparing to pristine pure sample. In contrast to pure samples, an anomalous second magnetization peak (SMP) effect is observed in both 1% and 2% Mn doped samples at T = 3 K for H∥ab but not for H∥c. Referring to Dew-Hughes and Kramer's model, we performed scaling analyses of the vortex pinning force density vs magnetic field inmore »« less

Critical current density and vortex pinning in tetragonal ${FeS}_{1 ₋ x} {Se}_{x}$ ( $x = 0, 0.06$ )

Journal Article Wang, Aifeng ; Wu, Lijun ; Ivanovski, V. N. ; ... - Physical Review B

Here we report critical current density (J_c) in tetragonal FeS single crystals, similar to iron-based superconductors with much higher superconducting critical temperatures (T_c). The J_c is enhanced three times by 6% Se doping. We observe scaling of the normalized vortex pinning force as a function of reduced field at all temperatures. Vortex pinning in FeS and FeS_0.94Se_0.06 shows contribution of core-normal surfacelike pinning. Lastly, reduced temperature dependence of J_c indicates that dominant interaction of vortex cores and pinning centers is via scattering of charge carriers with reduced mean free path (δl), in contrast to K_xFe_2₋ySe₂ where spatial variations in T_cmore » (δT_c) prevails.« less

On the Origin of Enhanced Critical Current Density and Thermal-Activated Flux Flow in K{sub x}Fe{sub 2−y}Se{sub 2} Superconductors: the Effect of Quenching and Mn Doping

Journal Article Fang, Y. F., E-mail: yifei-fang@fudan.edu.cn ; Li, M. T., E-mail: mingtaoli04@gmail.com - Journal of Superconductivity and Novel Magnetism

A magnetotransport, vortex pinning, and critical current density study of superconducting K{sub 0.8}Fe{sub 2−z}Mn{sub z}Se{sub 2} (z = 0, 0.02) single crystals is reported. The parameters of upper critical field, coherence length, and anisotropic ratio at 0 K are presented. Based on thermally activated flux flow model, the values of pinning potential, U{sub 0}{sup ∥{sub c}}(U{sub 0}{sup ∥{sub a}{sub b}}), at 0.25 T are derived to be as large as 1.3 × 10{sup 4}(1.8 × 10{sup 4}) K for z = 0.02, which shows rather robust and retains still larger than pure ones up to 9 T.

Flux pinning by Y[sub 2]BaCuO[sub 5] precipitates and field- and temperature-driven pinning centers in melt-powder-melt-growth processed YBa[sub 2]Cu[sub 3]O[sub 7]

Journal Article Kung, P J ; Maley, M P ; McHenry, M E ; ... - Physical Review, B: Condensed Matter; (United States)

Magnetic hysteresis, flux pinning, and flux creep in melt-powder-melt-growth processed YBa[sub 2]Cu[sub 3]O[sub 7] (Y 1:2:3) containing nominal 0, 25, and 40 mol % concentration of Y[sub 2]BaCuO[sub 5] (Y 2:1:1) inclusions were investigated. The strong pinning due to 2:1:1-phase precipitates in these samples allows for characterization of the hysteretic response as a function of pinning-site concentration over a large portion of magnetic-field--temperature space. We have found the following: (i) The curves of effective pinning energy [ital U][sub eff] versus current density [ital J] reveal a diverging behavior of [ital U][sub eff]([ital J]) in the low-[ital J] regime.
