Dynamics of magnetic domain wall motion after nucleation: dependence on the wall energy.

The dynamics of magnetic domain wall motion in the FeNi layer of a FeNi/Al2O3/Co trilayer has been investigated by a combination of x-ray magnetic circular dichroism, photoelectron emission microscopy, and a stroboscopic pump-probe technique. The nucleation of domains and subsequent expansion by domain wall motion in the FeNi layer during nanosecond-long magnetic field pulses was observed in th...

Metastable magnetic domain wall dynamics

The dynamics of metastable magnetic domain walls in straight ferromagnetic nanowires under spin waves, external magnetic fields and currentinduced 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 w...

Universality classes of magnetic domain wall motion.

We examine magnetic domain wall motion in metallic nanowires Pt-Co-Pt. Regardless of whether the motion is driven by either magnetic fields or current, all experimental data fall onto a single universal curve in the creep regime, implying that both the motions belong to the same universality class. This result is in contrast to the report on magnetic semiconductor (Ga,Mn)As exhibiting two diffe...

Micromagnetic simulations of magnetic domain wall dynamics

This summer project reproduces the foam experiment from previous summer but with oilwater emulsions. Increasing the viscosity of oil changes the droplets from soft to hard as well as the behavior from Newtonian liquid to granular matter. The expected outcome is Bachelor’s or Master’s Thesis or similar report depending on applicant’s background. The applicant is expected to have keen interest in...

Droplet nucleation and domain wall motion in a bounded interval.

We study a spatially extended model of noise-induced magnetization reversal: a classical Ginzburg-Landau model, restricted to a bounded interval and perturbed by weak spatiotemporal noise. By adapting the Coleman-Langer approach to false vacuum decay, we determine the dependence of the activation barrier and Kramers rate prefactor on the interval length. As it increases, a transition between ac...
