We found from analytical derivations and micromagnetic numerical simulations that there
exist two distinct normal modes in apparently complex vortex gyrotropic motions in two …

Microwave spectroscopy of individual vortex-state magnetic nanodisks in a perpendicular
bias magnetic field H is performed using a magnetic resonance force microscope. It reveals …

The coupling of two nonidentical magnetic nanodisks, ie, with different vortex gyrotropic
frequencies, is studied. From the analytical approach, the interactions between the …

The dynamics of magnetostatically coupled vortices in two nanodisks is here investigated
analytically and numerically. The rigid vortex model is employed to calculate the …

We studied, by micromagnetic numerical calculations, asymmetric vortex-core reversals
driven by the m=− 1 and m=+ 1 azimuthal spin-wave modes' excitations in soft magnetic …

The superparamagnetic limit imposes a restriction on how far the miniaturization of
electronic devices can reach. Recently it was shown that magnetic thin films with nanoscale …

We found, by micromagnetic numerical and analytical calculations, that the clockwise (CW)
and counterclockwise (CCW) circular-rotational motions of a magnetic vortex core in a soft …

Magnetic vortices are typically the ground states in geometrically confined ferromagnets with
small magnetocrystalline anisotropy. In this article I review static and dynamic properties of …

Defects introduced in ferromagnetic nanodisks may deeply affect the structure and dynamics
of stable vortexlike magnetization. Here, analytical techniques are used for studying, among …

We report a systematic control of the chirality of circular magnetic disks where dipole field
coupling drives the functionality. Our approach involves the use of two rhomboid …
