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…
Crossed ratchet effects for magnetic domain wall motion
A. Perez-Junquera, V. I. Marconi, A. B. Kolton +8
We study both experimentally and theoretically the driven motion of domain walls in extended amorphous magnetic films patterned with a periodic array of asymmetric holes. We find t…
