“…The detailed doping effect of each dopant is usually related to its phase transformation and existence pattern in the REBCO regime. Jongprateep et al [15] reported additions of small quantities of Nd 2 O 3 into Pt-doped Y-123, and nanosized (30-60 nm) second-phase precipitated particles were observed in the Nd-Y-123 matrix. Hu et al [16] reported the addition of ZrO 2 nanoparticles into air-processed Gd-123 superconductors, and the results proved that the ZrO 2 nanoparticles could react with Gd-123 and yield BaZrO 3 , which disperses in Gd-123 crystals with a size of less than 50 nm and leads to enhanced flux pinning.…”

The doping effect of BiFeO3 (BFO) nanoparticles on the growth and properties of Y–Ba–Cu–O (YBCO) superconductors by the powder melt and infiltration growth technique is investigated. The results indicate that nano-BFO doping reduces the growth rate of the Y-123 crystal and finally leads to smaller grain size in the YBCO bulk. Superconducting property measurements prove that improved levitation force and trapped field properties are observed in the 0.2 wt% BFO-doped YBCO sample. Magnetization measurement shows that the YBCO samples exhibit decreased T c values with the increased BFO amount from 0.1 wt%–0.3 wt%, but the transition width ΔT c shows no evident change. The sample with 0.2 wt% BFO addition presents the largest zero-field J c value and also the highest secondary peak value, which accounts for the superior performance of the sample. The electron probe micro analysis results combined with the XRD analysis prove the decomposition of the BFO and formation of the YBi-2411 in the final bulk, while Fe element exists in the form of Fe/Cu substitutions. Thus, the simultaneous introduction and cooperation of the two types of flux pinning centers (i.e. non-superconducting inclusions and element substitutions) can be realized through the addition of nano-BFO.

“…As many attempt to improve the synthesis conditions of Y123 superconducting powder and bulk samples, the synthesis method such as MTG(Melt Texture Growth) [4], MCP(Melt Condenser Processing) [5],, LPP( Liquid Phase Processing) [6], TSMG(Top Seed Melt Growth) ) [7], etc have been widely applied. Additionally, addition of AgO 2 (silver oxide) to Y123 compound is also responsible for several improvements in the superconductors such as electrical, mechanical and structural properties [8].…”

The Y3-8-11 superconductors and silver composite superconductors were synthesized by solid state reaction. The standard four probes method was used to measure the critical temperature (Tc), and the XRD technique (FULLPROF PROGRAM) was used to determine the lattice parameters, space group and phase compositions. It was found that the pure Y3-8-11 has the lowest Tc onset about 95 K, and the more silver doped concentration, have the higher Tc offset and Tc onset. The samples have both superconducting phase and non-superconducting phase. The silver doped samples have higher superconducting phase. The Pmmm space group was corresponding as to superconducting phase. The non-superconducting phase exhibite in Y211 and BaCuO2 with Pbnm and Im-3m, respectively. The surface of the silver doped sample is much smoother and denser compared to the undoped samples without impurities.

“…Alternatively, a seed of the single crystal process should provide a massive material in a reduced time. This means that the drive-force should be commonly called as a top seed melt growth [26][27][28][29][30][31].…”
