Current reversal in collective ratchets induced by lattice instability
L. Dinis, E. M. Gonzalez, J. V. Anguita +2
A collective mechanism for current reversal in superconducting vortex ratchets is proposed. The mechanism is based on a two-dimensional instability of the ground state (T=0) of the…

Lattice effects and current reversal in superconducting ratchets
L. Dinis, E. M. Gonzalez, J. V. Anguita +2
Competition between the vortex lattice and a lattice of asymmetric artificial defects is shown to play a crucial role in ratchet experiments in superconducting films. We present a…

Experimental ratchet effect in superconducting films with periodic arrays of asymmetric potentials
J. E. Villegas, E. M. Gonzalez, M. P. Gonzalez +2
A vortex lattice ratchet effect has been investigated in Nb films grown on arrays of nanometric Ni triangles, which induce periodic asymmetric pinning potentials. The vortex lattic…
