Abstract

We report the realization of a microstructure which leads to very strong high-temperature flux pinning in ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ crystals. Aligned discontinuous columns of damaged material, about 50 \AA{} in diameter and more than 15 \ensuremath{\mu}m long, are pro...
