Vortex pinning and vortex channeling in twinned YBa2Cu3O7

We analyze the effects of correlated disorder on the vortex dynamics in twinned YBa2Cu3O7 crystals by means of susceptibility experiments probing the compression mode of the lattice. When the magnetic field is oriented around the direction of the twin boundaries, the shielding (|χ′|) shows a relativ...
