Flux Pinning Characteristics in Tl Series Superconductors

Flux Pinning Characteristics in Tl Series Superconductors

Magnetic hysteresis and flux creep characteristics were measured with partially-melted Tl 1223 and solid-state-reacted Tl 2223 superconductors at 77 K. The Tl 1223 sample shows large magnetic hysteresis which linearly depends on sample thickness, and less time decay of magnetization, though the samp...

Zusammenfassung:Magnetic hysteresis and flux creep characteristics were measured with partially-melted Tl 1223 and solid-state-reacted Tl 2223 superconductors at 77 K. The Tl 1223 sample shows large magnetic hysteresis which linearly depends on sample thickness, and less time decay of magnetization, though the sample has many grain boundaries.
