The dynamics of metastable magnetic domain walls in straight ferromagnetic nanowires under spin waves, external magnetic fields and current- induced spin-transfer torque are studied by means of micromagnetic simulations. It is found that in contrast to a stable wall, it is possible to displace a metastable domain wall in the absence of external excitation. In addition, independent of the domain wall excitation method, the velocity of a metastable wall is much smaller than that of a stable wall… 
Domain wall dynamics driven by spin transfer torque and the spin-orbit field.
Using a one-dimensional model of a domain wall together with micromagnetic simulations, it is shown that the existence of such in-plane magnetic fields can either lower or raise the threshold current needed to cause domain wall motion.
Micromagnetic modeling of domain wall motion in sub-100-nm-wide wires with individual and periodic edge defects
Reducing the switching energy of devices that rely on magnetic domain wall motion requires scaling the devices to widths well below 100 nm, where the nanowire line edge roughness (LER) is an inherent
Direct imaging of the interaction between spin wave and transverse wall in magnetic nanostrip.
The dynamical interaction between spin wave and a transverse wall in a magnetic nanostrip is studied and the frequency-response curves of the SW-induced TW oscillation, SW reflection coefficient and TW velocity driven by SW share the same multiple-resonance property.

Dynamic scaling of ferromagnetic micro-rod clusters under a weak magnetic field.
The dynamic process of ferromagnetic microrod clusters under an external magnetic field was studied as a function of the cluster size N and the applied field B, and a theoretical model based on an extension of a zig-zag chain was developed that can be used to predict other cluster dynamics or the magneto-elastic behavior of other soft matters consisting of FMRCs.

We have designed a system to study microwave assisted domain wall nucleation in permalloy nanowires. We find a substantial decrease in the nucleation field when microwave fields are applied, in


Domain-wall dynamics driven by adiabatic spin-transfer torques
In a first approximation, known as the adiabatic process, the direction of the spin polarization of currents is parallel to the local magnetization vector in a domain wall. Thus the spatial variation

It is shown that domain walls move surprisingly long distances of several micrometers and relax over several tens of nanoseconds, under their own inertia, when the current stimulus is removed.

Theory of current-driven domain wall motion: spin transfer versus momentum transfer.
A self-contained theory of the domain wall dynamics in ferromagnets under finite electric current is presented and the momentum-transfer effect dominates, and the threshold current for wall motion is proportional to V(0)/rho(w), V0 being the pinning potential.
Magnetic domain walls displacement: Automotion versus spin-transfer torque
From the magnetization dynamics equation, a domain wall that changes structure is predicted to undergo a displacement by itself, a phenomenon called automotion. We experimentally demonstrate this
Resonant Amplification of Magnetic Domain-Wall Motion by a Train of Current Pulses
It is shown that by using a short train of current pulses, whose length and spacing are tuned to this precession frequency, the domain wall's oscillations can be resonantly amplified, making possible the motion of domain walls with much reduced currents, more than five times smaller than in the absence of resonant amplification.
