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.
自高温超导发现以来，基于稀土钡铜混合氧化物（REBCO）的薄膜超导体制造取得了重大进展。在我们的综述中，我们描述了通过引入纳米尺寸钉扎中心来改善超导性能的方法和可能性。我们重点关注用于人工钉扎中心的材料的合成及可行性，以及将钉扎中心引入基于REBCO的超导薄膜的方法。本文总结了现有材料和程序，而不考虑各方法的财务成本。根据现有文献，当将一维和零维纳米颗粒组合用于纳米级钉扎时，可获得最显著的超导REBCO带材。
