| Summary: | In this work, we have done simulations to monitor a domain wall’s motion in a cylindrical nanowire in the presence of magnetic field and current.
The domain wall of a nanowire alone will oscillate slightly and annihilate intrinsically. With the introduction of transverse magnetic field, produces 2 regimes of significant oscillations. There are the amplification regime, Regime 1, and the damping regime, Regime 2.
With the introduction of an opposing electron, it has effects on the periods, amplitude in the respective regimes and most importantly the duration of the regimes. From the findings, it suggests the existence of a current magnitude produce a possible constant AC output. |
