Oxygen deficiency x and its effect on Tc in superconducting Y Ba2Cu3O7-y
- 1. Toho Univ., Funabashi, Chiba (Japan). Faculty of Science
Description
Y3+ ion is substituted with Ca2+ ion in Y Ba2Cu3O7-y, where the ionic radii of both ions are almost the same. The substitution does not change the average valence of Cu ion, but the amount of oxygen deficiency y increases linearly with x up to x = 0.15. Crystal structure, critical temperature Tc, magnetization, y, electrical resistivity, and Hall effect were measured for the Ca system, and an abrupt increase in Hall mobility was observed at y = 0.56 corresponding to the sharp change of y there
