Domain-wall-assisted giant magnetoimpedance of thin-wall ferromagnetic nanotubes

epl draft Domain wall motion in thin ferromagnetic nanotubes: Analytic results

Dynamics of magnetization domain walls (DWs) in thin ferromagnetic nanotubes subject to weak longitudinal external fields is addressed analytically in the regimes of strong and weak penalization. Exact solutions for the DW profiles and formulas for the DW propagation velocity are derived in both regimes. In particular, the DW speed is shown to depend nonlinearly on the nanotube radius. The prob...

Currents induced by domain wall motion in thin ferromagnetic wires

Historically the role of eddy currents in the motion of Bloch walls has been extensively studied. In contrast the direct interaction of currents with such a moving wall has received very little attention. However recently it has been shown that a wall can be displaced by the effects of a current alone, a fact which is important to the development of spintronics. We report here that such a movin...

Current-Assisted Domain Wall Motion in Ferromagnetic Semiconductors

Single-wall Carbon Nanotubes with Ferromagnetic Electrodes

The electron transport in single-wall carbon nanotubes is one-dimensional and ballistic. Typically carbon nanotubes form tunneling contacts to electrodes and behave as quantum dots at low temperatures. We report on experiments on carbon nanotubes contacted with ferromagnetic metal. In these devices strong hysteretic magnetoresistance is observed at low temperatures. A possible interpretation of...
