Abstract
We report effects of heavy-ion irradiation in Ba(Fe1−xCox)2As2 single crystals. The columnar defects with about 40% of the irradiation dose are confirmed by transmission electron microscopy. Magneto-optical imaging and bulk magnetization measurements reveal strong enhancement of the critical current density in the irradiated region. The vortex creep rate is also strongly suppressed by the columnar defects. Effects of heavy-ion irradiation into Ba(Fe1−xCox)2As2 and cuprate superconductors are compared.
