This article reports the role of adding one-dimensional titanium dioxide nanowires (TiO₂-NWs, having 30 nm in diameter and some micrometers in length) on FC-ZFC magnetization, frequency-dependent AC susceptibility, and electrical measurements of the YBCO bulk system. The non-added (A0) and added TiO₂-NWs samples (A1) were prepared by solid-state reaction route. TiO₂-NWs did not affect the crystalline structure of YBCO. SEM examinations revealed that TiO₂-NWs preferred to localize at the grain boundaries filling the pores existing between YBCO grains. FC-ZFC magnetization and frequency-dependent AC susceptibility analysis showed an enhancement of flux pinning properties with TiO₂-NWs addition. TiO₂-NWs addition affected also the electrical and pseudo-gap analysis of the samples.

本文报告了添加一维二氧化钛纳米线（TiO ₂ -NW，直径为 30 nm，长度为几微米）对 FC-ZFC 磁化、频率相关的交流磁化率和 YBCO 本体系统的电气测量的作用. 未添加（A0）和添加的TiO ₂ -NWs 样品（A1）通过固态反应途径制备。TiO ₂ -NWs 不影响YBCO 的晶体结构。SEM 检查表明，TiO ₂ -NWs 更倾向于定位在填充 YBCO 晶粒之间存在的孔隙的晶界处。FC-ZFC 磁化强度和频率相关的 AC 磁化率分析表明，添加 TiO ₂ -NW可增强磁通钉扎性能。二氧化钛_2- NWs 的添加也影响了样品的电气和伪间隙分析。
