Transverse ratchet effect and superconducting vortices: Simulation and experiment
L. Dinis, D. Perez de Lara, E. M. Gonzalez +3
A transverse ratchet effect has been measured in magnetic/superconducting hybrid films fabricated by electron beam lithography and magnetron sputtering techniques. The samples are…
Control of the chirality and polarity of magnetic vortices in triangular nanodots
M. Jaafar, R. Yanes, D. Perez de Lara +6
Magnetic vortex dynamics in lithographically prepared nanodots is currently a subject of intensive research, particularly after recent demonstration that the vortex polarity can be…
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…
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…
