Melt Processing of YBaCuO Oxide Superconductors

Stress–strain behavior under static loading in Gd123 high-temperature superconductors at 77K

“…High temperature superconductors (HTS conductors) have been developed for high performance superconducting devices [1][2][3][4][5][6][7][8][9]. Understanding of mechanical, electric and magnetic properties of HTS conductors and improvements of evaluation techniques for these properties are important for the development of superconducting devices.…”

Continuous solidification of YBa2Cu3O7−x by isothermal undercooling

“…[1][2][3] Strong magnetic flux pinning capacity and high levitation forces are achieved by increasing the J c and the loop size of the circulating current in Y123 single crystals. Hence, introducing of effective flux pinning sites for the enhancement of J c , particularly in high magnetic fields, as well as enlargement of the crystal size are necessary for more demanding applications of high critical temperature, T c , superconductors.…”

Effect of zirconium diffusion on the microstructural and superconducting properties of YBa2Cu3O7−δ superconductors

“…However, the latter property is inadequately low in the YBCO samples due to the serious weak links and the granularity. Therefore, for years several methods including chemical doping, substitution, transition metal evaporation and changing preparation condition have been developed to produce the effective pinning centers such as planar defects, stacking faults and micro-defects [13][14][15][16][17]. The evaporation method, among the others, is one of the most preferred techniques owing to the reproducible process of the samples accomplished quite easily compared to the other methods [18][19][20] and the controlled doping at relatively low concentrations (10 16 -10 21 cm À3 ).…”
