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…
Chiral asymmetry detected in a 2D array of permalloy square nanomagnets using circularly polarized X ray Resonant Magnetic Scattering
J. Díaz, P. Gargiani, C. Quirós +8
The sensitivity of Circularly polarized X ray Resonant Magnetic Scattering (CXRMS) to chiral asymmetry has been demonstrated. The study was performed on a 2D array of Permalloy (Py…
Revealing 3D Magnetization of Thin Films with Soft X-ray Tomography: Closure Domains and Magnetic Singularities
A. Hierro-Rodriguez, C. Quirós, A. Sorrentino +7
The knowledge of how the magnetization looks inside a ferromagnet is often hindered by the limitations of the available experimental methods that are sensitive only to the surface…
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…
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…
Double percolation effects and fractal behavior in magnetic/superconducting hybrids
L. Ruiz-Valdepeñas, M. Velez, F. Valdes-Bango +5
Perpendicular magnetic anisotropy ferromagnetic/ superconducting (FM/SC) bilayers with a labyrinth domain structure are used to study nucleation of superconductivity on a fractal n…
