Spintronics is a quantum technology which aims at adding the spin degree of freedom to conventional CMOS electronics. Since discovery giant magneto-resistance in 1988, considered as birth this field, spintronics continues flooding market with plethora devices used everyday life applications such hard drive read heads or magnetic random-access memories, and so on. From fundamental research persp...

Abstract Enhancement of magneto-optical effects in hybrid magneto-plasmonic systems has attracted considerable recent attention because their potential for building non-reciprocal nanophotonic devices. Quantitative understanding the fundamental origin and contributing mechanisms enhancement is crucial optimizing applications. Here, we unravel different physical origins giant Faraday rotation el...

The adductor muscles of the pectoral fins of the hatchetfish Gasteropelecus are innervated by bilateral pools of about 40 motoneurons which lie primarily in the first spinal segment. A pair of giant fibers on each side of the medulla send processes ventroposteriorly to the motoneuron pools. Electrophysiological evidence indicates that giant fibers are presynaptic to ipsilateral motoneurons, but...

We present a theoretical and experimental study on the biosensing sensitivity of Au/Co/Au multilayers as transducers of the magneto-optic surface-plasmon-resonance (MOSPR) sensor. We demonstrate that the sensing response of these magneto-plasmonic (MP) transducers is a trade-off between the optical absorption and the magneto-optical activity, observing that the MP multilayer with larger MO effe...

Superradiance—the cooperative decay of excited dipoles—has recently been discussed in a diverse range of contexts in which coherent coupling of constituent particles governs their cooperative dynamics: cavity quantum electrodynamics, quantum phase transitions and plasmonics. Here we observe intense, delayed bursts of coherent radiation from a photo-excited semiconductor and interpret it as supe...

The giant magneto-impedance (GMI) effect has been studied in 3 different families of amorphous wires: conventional amorphous wires (125 μm in diameter), cold drawn wires (50 and 20 μm in diameter) and thin glass coated amorphous microwires (with metallic nucleus diameter of about 15 μm). These wires have been investigated in the frequency range 1 – 500 MHz. A remarkable difference in the magnet...

A bi-component nanostructured system composed by a Co dot array embedded in a Ni80Fe20 antidot matrix has been prepared by means of the self-assembling polystyrene nanospheres lithography technique. Reference samples constituted by the sole Co dots or Ni80Fe20 antidots have also been prepared, in order to compare their properties with those of the bi-component material. The coupling between the...

We demonstrate that the giant magnetoresistance can be switched off (on) in even- (odd-) width zigzag graphene-like nanoribbons by an atomistic gate potential or edge disorder inside the domain wall in the antiparallel (ap) magnetic configuration. A strong magneto-thermopower effect is also predicted that the spin thermopower can be greatly enhanced in the ap configuration while the charge ther...
