We review and extend the theory of chiral pumping spin waves by magnetodipolar stray fields that generate unidirectional currents asymmetric magnon densities. illustrate physical principles two kinds excitations magnetic films, i.e., evanescent Oersted field a narrow metallic stripline with an AC current bias nanowire under ferromagnetic resonance.

Abstract There has been recent interest in superconductor-magnetic insulator hybrid Rashba nanowire setups for potentially hosting Majorana zero modes at smaller external Zeeman fields. Using the non-equilibrium Green’s function technique, we develop a quantum transport model that accounts interplay between quasiparticle dynamics bilayer structure and processes through nanowire. We provide an a...
A highly sensitive and large working range giant magnetoimpedance (GMI) effect is found in the novel nanostructure: nanobrush. The nanostructure is composed of a soft magnetic nanofilm and a nanowire array, respectively fabricated by RF magnetron sputtering and electrochemical deposition. The optimal GMI ratio of nanobrush is promoted to more than 250%, higher than the pure FeNi film and some s...
We study proximity-induced superconductivity in gold nanowires as a function of the length of the nanowire, magnetic field, and excitation current. Short nanowires exhibit a sharp superconducting transition, whereas long nanowires show nonzero resistance. At intermediate lengths, however, we observe two sharp transitions; the normal and superconducting regions are separated by what we call the ...
