| Abstract | Single-domain YBCO superconductors with different additions of nanometer Y $_{2}$Ba $_{4}$CuNbO $_{ x }$(YNb2411), based on the solid phase of [(100-x)Y $_{2}$BaCuO $_{5}$(Y211) + x YNb2411] (x = 3, 5, 7, 10, 12) and liquid phase of (Y211 + 9BaCuO $_{2}$ + 6CuO), were successfully fabricated by a modified top seeded infiltration and growth process (TSIG), the growth morphology, microstructure, levitation force and the trapped magnetic field were investigated in details. Results indicate that single-domain YBCO superconductors can be fabricated with x ≤ 7 wt % but random nucleation of YBCO crystal occurs near the edge of the sample and seriously reduced the size of the single domain grown from the NdBCO seed when x ≥ 10 wt %. The YNb2411 particles were successfully introduced into the YBCO matrix, and the size of the YNb2411 particles embedded in the YBCO matrix is about 300 nm. However, agglomeration usually occurs when the addition of YNb2411 ≥ 10 wt %. As a result, the levitation force increases firstly from 32 to 42.5 N and then reduces down to 7 N with the increasing of YNb2411 additions from 3 to 7 wt % and 12 wt %. The results are helpful to improve the properties of YBCO bulk superconductors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
