Enhancement of vortex liquid phase and reentrant behavior in NiBi3 single crystals
V. Rollano, M. C. de Ory, A. Gomez +12
We investigated the vortex phase diagram of needle shaped high quality NiBi3 single crystals by transport measurements. The current is applied along the crystalline b-axis of this…
Realization of macroscopic ratchet effect based on nonperiodic and uneven potentials
V. Rollano, A. Gomez, A. Muñoz-Noval +5
Ratchet devices allow turning an ac input signal into a dc output signal. A ratchet device is set by moving particles driven by zero averages forces on asymmetric potentials. Hybri…
Little-Parks Effect Governed by Magnetic Nanostructures with Out-of-Plane Magnetization Little-Parks Effect Governed by Magnetic Nanostructures with Out-of-Plane Magnetization
M. C. de Ory, V. Rollano, A. Gomez +4
Little-Parks effect names the oscillations in the superconducting critical temperature as a function of the magnetic field. This effect is related to the geometry of the sample. In…
Vortex dynamics controlled by local superconducting enhancement
V. Rollano, A. Gomez, A. Muñoz-Noval +7
A controlled local enhancement of superconductivity yields unexpected modifications in the vortex dynamics. This local enhancement has been achieved by designing an array of superc…
Magnetic order and disorder in nanomagnets probed by superconducting vortices
V. Rollano, J. del Valle, A. Gomez +8
We have studied two nanomagnet systems with strong (Co/Pd multilayers) and weak (NdCo alloy films) stray magnetic fields by probing the out-of-plane magnetic states with supercondu…
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…
