“…The conventional Y-based superconducting material, Y123 (YBa 2 Cu 3 O 7-x ), was the first superconductor found in 1987, exhibiting a critical temperature above 90 K [3]. Numerous researchers have conducted studies and advancements to enhance the superconducting properties of Y-based materials for various fields of application, including superconducting magnetic bearings [4], superconducting electric motors [5], magnetic separation devices [6], non-contact transport systems [7], and flywheel energy storage systems [8], among others. In 2013, Kruaehong [9] successfully synthesized bulk Y-based superconductors of Y257 through a solid-state reaction method.…”

Y211 was added to the Y257 superconducting material at concentrations of 0, 0.10, and 0.20 mol using a solid-state reaction synthesis method. As the concentration of Y211 increased, both the onset critical temperature and the offset critical temperature decreased. The synthesized samples contained a combination of superconducting and non-superconducting compounds. The superconducting compound exhibited an orthorhombic structure with the Pmmm space group. Additionally, three different types of non-superconducting compounds were identified in the samples. The percentage of non-superconducting compounds increased with the addition of Y211. The surface morphology revealed heterogeneous elements and a random distribution of grain sizes. The samples contained Y, Ba, Cu, and O elements without any detectable impurities.

“…This superconductor has highest critical temperature about 94K. Because superconducting properties of the Y123, Y358, and Y257 can be performed in liquid nitrogen, this cheap cryogenic medium makes the materials promising in many fields such as superconducting magnetic bearings (Jiqiang et al, 2012), superconducting electric motors (Hiroyuki and Yuichi, 2001), magnetic separation devices (Oka et al, 2013), non-contact transport systems (Smith and Jr. Dolan, 2013), flywheel energy storage systems (Arai et al, 2013) and permanent magnets with high trapped field (Liu et al, 2011) operating above 77K (Moon and Chang, 1990;Hull, 2001).…”

The Y123, Y358 and Y257 bulk superconductors mixed with various ratio of non-superconducting Y211 (Y 2 BaCuO 5 ) were synthesized by solid state reaction. The physical properties of pellets were investigated by d.c. four-probes measurement. The crystal structure was determined using powder X-ray diffraction and the characteristic peaks were determined using the Rietveld full-profile analysis method. Results showed that the T c onset and T c offset decreased with the increasing of Y211 doping. The samples consist of both superconducting phase and the non-superconducting phase. The lattice parameter of Y211 doped samples showed lower c direction than pure samples. The superconducting phase decreased with increasing Y211 content. The non-superconducting phases consists of Pccm (Ba 2 Cu 3 O 6) and Im-3m (BaCuO 2 ) respectively. According to the percentage of superconducting phase, the anisotropy increased with Y211 contents.
