Vortex-glass transition in superconducting Nb/Cu superlattices
J. E. Villegas, J. L. Vicent
Nb/Cu superconducting superlattices have been fabricated by dc magnetron sputtering. This system shows a vortex glass transition with critical exponents similar to high temperature…

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…
