Current needs for further advances in the nanotechnologies of information-storage and-
processing devices have attracted a great deal of interest in spin (magnetization) dynamics …

We report direct imaging by means of x-ray photoemission electron microscopy of the
dynamics of magnetic vortices confined in micron-sized circular permalloy dots that are 30 …

We report a high-resolution experimental detection of the resonant behavior of magnetic
vortices confined in small disk-shaped ferromagnetic dots. The samples are magnetically …

A distinct type of solitary wave is predicted to form in spin torque oscillators when the free
layer has a sufficiently large perpendicular anisotropy. In this structure, which is a dissipative …

We conducted micromagnetic numerical studies on the strong radiation of spin waves (SWs)
produced by the magnetic-field-induced reversal of a magnetic vortex core, as well as their …

We show that the dynamic magnetization at the edges of a thin magnetic element with a
finite lateral size can be described by new effective boundary conditions that take into …

We have investigated azimuthal spin-wave modes in magnetic vortex structures using time-
resolved Kerr microscopy. Spatially resolved phase and amplitude spectra of ferromagnetic …

To verify the exact underlying mechanism of ultrafast vortex-core reversal as well as the
vortex state stability, we conducted numerical calculations of the dynamic evolution of …

Vortex dynamics in a restricted geometry is considered for a magnetic system consisting of
ferromagnetic cylindrical dots. To describe the vortex dynamic susceptibility and relaxation …

In experiments, the distinction between spin-torque and Oersted-field-driven magnetization
dynamics is still an open problem. Here, the gyroscopic motion of current-and field-driven …
