Oxygen dependence of the Josephson weak link effect, specific heat, and the transition temperature of YBa sub(2)Cu sub(3)O sub(x)

Oxygen dependence of the Josephson weak link effect, specific heat, and the transition temperature of YBa sub(2)Cu sub(3)O sub(x)

YBa sub(2)Cu sub(3)O sub(x) samples were sintered in air, annealed in oxygen at different temperatures, and annealed under high vacuum. The temperature dependence of the magnetic susceptibility and the specific heat was measured. The results for these samples are discussed in terms of variations in...

Zusammenfassung:YBa sub(2)Cu sub(3)O sub(x) samples were sintered in air, annealed in oxygen at different temperatures, and annealed under high vacuum. The temperature dependence of the magnetic susceptibility and the specific heat was measured. The results for these samples are discussed in terms of variations in their oxygen content.
