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…
Topologically protected superconducting ratchet effect generated by spin-ice nanomagnets
V. Rollano, A. Muñoz-Noval, A. Gomez +7
We have designed, fabricated and tested a robust superconducting ratchet device based on topologically frustrated spin-ice nanomagnets. The device is made of a magnetic Co honeycom…
