“…Artificial pinning with the usage of noble metals, such as silver [126][127][128][129], gold [130][131][132], palladium [133], or platinum [134,135], is known to be possible, with the major disadvantage being that noble metals are quite expensive. The usage of inert ceramics from the same REBCO system is also a possibility, for instance in the case of YBCO system, phase Y-2411-M (Y 2 Ba 4 CuMO x ), where M = Nb, Ta, Mo, W, Ru, Zr, Bi and Ag phase seems to be a promising material [136][137][138][139][140][141][142]. Similarly, inert perovskite phases (stable at high temperatures) such as BaZrO 3 , Ba 2 RETaO 6 , Ba 2 Y (Nb, Ta)O 6 or BaTiO 3 have been also reported as prospective candidates for inert pinning centers [143][144][145][146].…”

Since the discovery of high-temperature superconductivity, significant progress in the fabrication of REBCO-based (Rare Earth Barium Copper mixed Oxides) thin-films superconductors has been achieved. In our review, we described the approaches and possibilities of the improvement of superconducting properties by the introduction of nanosized pinning centers. We focused on the synthesis and viability of the material for artificial pinning centers and methods used for the introduction of the pinning centers into superconducting REBCO-based thin-films. This article summarizes available materials and procedures regardless of the financial cost of the individual method. According to available literature, the most significant superconducting REBCO tapes can be obtained when a combination of 1D and 0D nanoparticles are used for nanoscale pinning.

“…However, the effective flux pinning force can be achieved only when the size of the particles is near the coherent length (ξab ≈ 2-4 nm below 77 K for REBCO bulk superconductors) [25][26][27]. To attain greater flux pinning performance, the RE 2 Ba 4 CuMO y (RE-2411) has been introduced in REBCO bulk superconductors as effective flux pinning centers [28][29][30][31][32][33]. Moreover, it has been partially demonstrated that the Y 2 Ba 4 CuNbO y (YNb2411) particles do not ripen during melt processing [34,35].…”

“…Babu et al found that the J c value of the GdBCO bulk superconductor reached 5.5 × 10 4 A cm −2 by adding Gd 2 Ba 4 CuNbO y [30,34,38]. To compare the influence of RE211 and RE2411 on the properties of the samples, the SmBCO bulk superconductors with the initial compositions of [70%Sm123 + 30%Sm211 + 2%BaO 2 ] and [70%Sm123 + 20%Sm211 + 10%Sm2411 + 2%BaO 2 ], the J c value of the samples with Sm2411 particles was 7.25 × 10 4 A cm −2 , which was more than three times that of the samples that were only doped with Sm211 [32].…”

In this work, a new kind of YGdBa4CuNbOy (YGdNb-11411) nano-particles was designed and sintered using a solid-state reaction method, whereas their impact on the performance of GdBCO bulks was investigated for the first time. From the acquired XRD data and SEM imaging results, it was proved that the YGdNb-11411 particles were of excellent chemical stability and did not react with other phases during the crystal growth process. The YGdNb-11411 particles ranged from 80 to 130 nm and they were uniformly distributed in the well-textured GdBCO bulk superconductors. The maximum critical current density (Jc-max) of the samples was enhanced from 3.48 × 104 A/cm2 to 8.63 × 104 A/cm2 (77 K) in the self-field as the doping amount increased from 0wt% to 7wt%. In addition, the GdBCO sample with YGdNb-11411 particles also showed an enhanced flux pinning force density and relatively high Jc around the magnetic flux density range of 1 T - 2 T (77 K). These results clearly indicated that the YGdNb-11411 particles could effectively enhance the properties of the GdBCO bulk superconductors.
