Force-free state in a superconducting single crystal and angle-dependent vortex helical instability
J. del Valle, A. Gomez, E. M. Gonzalez +3
Superconducting 2H-NbSe2 single crystals show intrinsic low pinning values. Therefore, they are ideal materials with which to explore fundamental properties of vortices. (V, I) cha…
Effective penetration length and interstitial vortex pinning in superconducting films with regular arrays of defects
J. del Valle, A. Gomez, E. M. Gonzalez +1
In order to compare magnetic and non-magnetic pinning we have nanostructured two superconducting films with regular arrays of pinning centers: Cu (non-magnetic) dots in one case, a…
Different approaches to generate matching effects using arrays in contact with superconducting films
J. del Valle, A. Gomez, J. Luis- Hita +3
Superconducting films in contact with non-superconducting regular arrays can exhibit commensurability effects between the vortex lattice and the unit cell of the pinning array. The…
Experimental realization of smectic phase in vortex matter induced by symmetric potentials arranged in two-fold symmetry arrays
J. del Valle, A. Gomez, E. M. Gonzalez +4
Smectic order has been generated in superconducting Nb films with two-fold symmetry arrays of symmetric pinning centers. Magnetic fields applied perpendicularly to the films develo…
Superconducting/magnetic three state nanodevice for memory and reading applications
J. del Valle, A. Gomez, E. M. Gonzalez +3
We present a simple nanodevice that can operate in two modes: i) three-state memory and ii) reading device. The nanodevice is fabricated with an array of ordered triangular-shaped…
Vortex pinning vs superconducting wire network: origin of periodic oscillations induced by applied magnetic fields in superconducting films with arrays of nanomagnets
A. Gomez, J. del Valle, E. M. Gonzalez +6
Hybrid magnetic arrays embedded in superconducting films are ideal systems to study the competition between different physical (such as the coherence length) and structural length…
