Ultra-fast growth (up to 100 nm s⁻¹) of high temperature superconducting film was demonstrated by using an advanced pulsed laser deposition technique. Highly textured EuBa₂Cu₃O_7−δ (EuBCO) film with 8 mol.% of BaHfO₃ (BHO) was deposited on the IBAD-based Hastelloy substrates. Structure characterizations reveal formation of high density of BHO nanocolumns with diameter of ∼5 nm in the film, which is well beyond the expectation. Comparison study on different amount of BHO in EBCO film confirmed that nanocolumn formation strongly depends on the dopant level. The epitaxial growth process of BHO is dominated by ultra-fast self-assembly associated with enhanced diffusion of high flux element and liquid phase. Due to the correlated pinning landscape, a pronounced broad peak appears at B//c in the J _c(θ) curves at 30 K 5 T, while a strong pinning force of about 900 GN m⁻³ at 4.2 K, 10 T (B//c) are achieved.

通过使用先进的脉冲激光沉积技术证明了高温超导薄膜的超快速生长（高达 100 nm s ^-1）。具有 8 mol.% BaHfO _{3 的}高度织构的 EuBa ₂ Cu ₃ O _{7− δ} (EuBCO) 膜(BHO) 沉积在基于 IBAD 的哈氏合金基板上。结构表征表明在薄膜中形成了直径约 5 nm 的高密度 BHO 纳米柱，这远远超出了预期。EBCO 膜中不同量 BHO 的比较研究证实，纳米柱的形成强烈依赖于掺杂剂水平。BHO 的外延生长过程由与高通量元素和液相增强扩散相关的超快自组装主导。由于相关的钉扎的景观，一个显着的宽峰出现在乙// Ç在Ĵ _Ç（θ）的曲线在30 K 5 T，而约900 GN米的强钉扎力^-3在4.2 K，10 T（乙//丙) 实现。
