Heavy-ion irradiation effects in Ag–Cu alloy sheathed Bi-2223 tapes

We have investigated the magnetic properties of Ag–Cu alloy sheathed Bi-2223 tapes with columnar defects parallel to the c-axis introduced by Xe-ion irradiation. We found that the irreversibility line in heavy-ion irradiated Bi-2223 tapes showed the shift toward higher fields. In addition, the irrev...

Description
Summary:We have investigated the magnetic properties of Ag–Cu alloy sheathed Bi-2223 tapes with columnar defects parallel to the c-axis introduced by Xe-ion irradiation. We found that the irreversibility line in heavy-ion irradiated Bi-2223 tapes showed the shift toward higher fields. In addition, the irreversibility curve of the irradiated Ag–Cu alloy sample is located in the higher temperature side of the irradiated Ag sheathed tape even in the higher magnetic field than the matching field.
