Abstract

The single inclusion of nanoparticles (NPs) into high-temperature superconductor materials was widely reported and proved its ability to enhance the pinning properties. The current research work aims to evaluate the influence of the combined addition effect of conductor (Ag) and insulator (

) NPs on the structure, morphology, critical current densities, and flux pinning properties of Ya₂Cu₃O_7-d (Y123) superconducting ceramics. We established that adding this route has a positive effect on the superconducting and pinning properties of the material. Specifically, it is observed that the co-addition of Dy₂O₃-Ag-NPs substantially enhances the critical current density by >330 % for in-field up to 3 Tesla and by 450 % for in-field up to 5 Tesla as compared to the pristine Y123 sample. Moreover, the energy of the centers that pin the vortex was strengthened and the critical current density at grain boundaries has also risen by more than ten times.

作为 YBa2Cu3O7-d 超导陶瓷高效引脚中心的绝缘体-导体（Dy2O3-Ag）纳米粒子的共添加物

在高温超导体材料中单一加入纳米粒子（NPs）的研究已被广泛报道，并证明了其增强引脚特性的能力。目前的研究工作旨在评估导体（Ag）和绝缘体（Dy2O3）纳米粒子的联合添加效应对 Ya2Cu3O7-d （Y123）超导陶瓷的结构、形态、临界电流密度和磁通引脚特性的影响。我们发现，添加这一途径对材料的超导和引脚特性有积极影响。具体来说，与原始的 Y123 样品相比，Dy2O3-Ag-NPs 的共同添加大大提高了临界电流密度，在高达 3 特斯拉的磁场中提高了 330%，在高达 5 特斯拉的磁场中提高了 450%。此外，漩涡中心的能量得到加强，晶界处的临界电流密度也提高了十倍以上。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
