Abstract
- Superconducting bulks can be magnetized to act as powerful permanent magnets; however, for high trapped fields at temperatures below 77 K, bulks have poor thermal stability and are limited by low mechanical strength. The trapped fields reported in this paper are between two stacks of commercial high-temperature superconducting tape each with 120 layers, magnetized by field cooling. 7.34 T was trapped at approximately 4.2 K, the highest field ever achieved for such a sample. The trapped field also continued to increase below 20 K showing high thermal stability, largely due to the silver over-layer which effectively dissipates heat. [ABSTRACT FROM AUTHOR]
