A quantitative understanding of the enhanced irreversibility line and critical current density due to linear defects in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} single crystals with the vortex dimensionality-crossover model
Abstract
We show that the 3D-to-2D crossover model of Kim et al. (Physics C177, 431, 1991) provides a quantitative understanding of recent results of Thompson et al. (Appl. Phys. Lett. 60, 2306, 1992) for both the enhanced irreversibility line and critical current density, J{sub c}, in single-crystalline Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} after heavy-ion irradiation. Fits of the irreversibility lines indicate that these linear defects increase the pinning energy by a factor of {approximately}4, which is also consistent with the low-temperature J{sub c} enhancement. Dependence of the pinning effectiveness on the nature of artificial or natural pinning sites is discussed.
