Title: Enhancement of critical current density in CaKFe₄As₄ single crystals through 3 MeV proton irradiation

Abstract

We study the influence of random point disorder on the vortex dynamics and critical current densities J _c of CaKFe₄As₄ single crystals by performing magnetization measurements. Different samples were irradiated with a proton (p) beam at constant energy of 3 MeV to fluencies from 2 × 10¹⁵ p cm^-2 to 4 × 10¹⁶ p cm^-2. The results show the addition of extrinsic random point disorder enhances the J _c values at low and intermediate temperatures over the entire range of magnetic fields applied. The optimum pinning enhancement is achieved with a proton fluence of 3 × 10¹⁶ p cm^-2, increasing J _c at 5 K by factors ≈5 and 14 at self-field and μ ₀ H = 3 T, respectively. We analyze the vortex dynamics using the collective creep theory. The enhancement in J _c matches with a systematic reduction in the flux creep relaxation rates as a consequence of a gradual increase in the collective pinning energy U ₀. The substantial increment in J _c produced by random point disorder, reaching values of 9 MA cm^-2 at 5 K and self-field, makes CaKFe₄As₄ a promising material for applications based on current carrying capacity at high magnetic fields.

Substantial reduction of the anisotropy in the critical current densities J_c of Ni-doped CaKFe₄As₄ single crystals by chemical and irradiation-induced disorder

Journal Article Haberkorn, N. ; Xu, M. ; Meier, W. R. ; ... - Superconductor Science and Technology

Here, we demonstrate that the anisotropy in the critical current densities, J_c, of CaK(Fe_1–xNi_x)₄As₄ (x = 0, 0.015, 0.025, and 0.030) single crystals reduces with increasing chemical and irradiation-induced disorder. The magnetic field dependences of J_c are analyzed by performing magnetization measurements with H applied parallel and perpendicular to the crystallographic c-axis. The results show that undoped crystals display large anisotropies in Jc due to an enhancement of the vortex pinning with H applied parallel to the crystallographic ab-planes. This anisotropy reduces substantially as Ni addition increases. Moreover, we found that random disorder introduced by proton irradiation enhances mainly themore »« less

Ultrahigh critical current densities, the vortex phase diagram, and the effect of granularity of the stoichiometric high-T_c superconductor CaKFe₄As₄

We present a comprehensive study of the critical current densities and the superconducting vortex phase diagram in the stoichiometric superconductor CaKFe₄As₄ which has a critical temperature of ~35 K. We performed detailed magnetization measurements both of high quality single crystals for different orientations in an applied magnetic field up to 16 T and for a powder sample. We find an extremely large critical current density, J_c, up to 10⁸ A/cm² for single crystals when H∥(ab) at 5 K, which remains robust in fields up to 16 T, being the largest of any other iron-based superconductor.

Strong pinning and slow flux creep relaxation in Co-doped CaFe₂As₂ single crystals

In this paper we report on measurements of critical current densities J_c and flux creep rates S of freestanding Ca(Fe_1–xCo_x)₂As₂ (x ≈ 0.033) single crystals with T_c ≈ 15.7 K by performing magnetization measurements. The magnetic field dependences of J_c at low temperature display features related to strong pinning. In addition, we find that the system displays small flux creep rates. The characteristic glassy exponent, μ, and the pinning energy, U₀, display exceptional high values for pristine crystals. We find that for magnetic fields between 0.3 T and 1 T, μ decreases from ≈ 2.8 to ≈ 2 and U₀more »« less

Chemical stability and superconductivity in Ag-sheathed CaKFe₄As₄ superconducting tapes

Journal Article Cheng, Zhe ; Dong, Chiheng ; Huang, He ; ... - Superconductor Science and Technology

Ag-sheathed CaKFe₄As₄ superconducting tapes have been fabricated via the ex situ powder-in-tube method. X-ray diffraction analyses suggest that the CaKFe₄As₄ phase reacts strongly with the silver sheath at temperature above 500 °C. We therefore anneal the tape at 500 °C and obtain a transport critical current density J _c(4.2 K, 0 T) ~ 2.7 × 10⁴ A cm^–2. The pinning potential derived from magnetoresistance measurements is one order of magnitude lower than that of the (Ba/Sr)_1–xK_xFe₂As₂ tapes. Combining with the scanning electron microscopy and magneto-optical imaging results, we suggest that bad connectivity between superconducting grains caused by the low sinteringmore »« less
