We have investigated the response of 3D Bi2Sr2CaCu2O8 vortex structures to a weak
perturbation induced by 2D Fe pinning structures acting on one extremity of vortex lines. The …

In extremely anisotropic cuprate superconductors a lattice of stacks of pancake vortices
nucleates when a magnetic field is applied perpendicular to the copper oxide layers, while …

The effect of a periodic pinning array on the vortex state in a two-dimensional
superconductor at low temperatures is studied within the framework of the Ginzburg-Landau …

We study the onset of the irreversible magnetic behavior of vortex matter in micron-sized Bi 2
Sr 2 CaCu 2 O 8+ δ single crystals by using silicon micro-oscillators. We find an …

Different configurations of columnar defects tilted with respect to c have been tailored in Bi 2
Sr 2 CaCu 2 O 8 single crystals by controlling the orientation of a heavy-ion beam: One …

We have performed Bitter decoration and ac susceptibility measurements in single-crystal
YBa 2 Cu 3 O 7− δ with oriented twin boundaries. The twin boundaries (TB's) pin vortices …

Local vortex dynamics in Bi 2 Sr 2 CaCu 2 O 8 single crystals was studied using novel
microscopic GaAs/AlGaAs Hall-sensor arrays. The irreversibility line (IL) is found to exist in …

We report investigations on the dynamics of vortex matter with periodic pinning in crystalline
Bi 2 Sr 2 CaCu 2 O 8 nanoribbons containing an array of nanoscale holes. We found that the …

The vortex patterns stabilized by a square array of artificial pinning sites with a tunable
pinning strength are studied by using a phenomenological approach in the London limit …

We study the general problem of a manifold of interacting elastic lines whose spatial
correlations are strongly affected by the competition between random and ordered pinning …
