Abstract

The transport critical current density (J_c) in Bi-2223 tapes with J_c(77K) ^∼ 10⁴ A/cm² was studied under hydrostatic pressure up to 14 kbar. The pressure dependence of the critical current density in Bi-2223 tapes is qualitatively different from that in YBCO ceramics and thin films. In Bi-2223 tapes J_c increases in the initial pressure range with pressure derivatives d(In J_c)/dP in the range 0.06-0.1 kbar^-1. At P^∼8-12 kbar J_c(P) turns to saturation, while the superconducting transition temperature increases linearly under pressure with dT_c/dP ^∼ 0.16-19 K/kbar in the entire v pressure range.

In Bi-2223 tapes Jc increases in the initial pressure range with pressure derivatives d(In Jc)/dP in the range 0.06-0.1 kbar-1.
