FIG. 1.

(Color online) Sketch of the nanocontact geometry.

FIG. 2.

(Color online) Main panel: (symbols) frequency vs current behavior for different anisotropy constant in the FL; (dotted lines) linear fits showing the current tunability for each of them. Inset: frequency vs wavenumber dispersion relation for the same anisotropy constants as in the main panel. Symbols are representatives of the data computed by using , whereas dotted lines are obtained by using Eq. (1).

FIG. 3.

(Color online) Inset: wavelength as function of the anisotropy constant together with the expression of its quadratic fit. Main panel: frequency as function of the anisotropy constant. Symbols are the simulated data and solid and dotted lines are the computed [by Eq. (1)] and the linear fits, respectively. Applied current .

Image of FIG. 4.
FIG. 4.

(Color online) (a) and (b) Details of the spatial distribution of the magnetization close to the contact area (the dotted circle in the figures) in two different time instants, showing the reversal of both polarization and gyration sense of the vortex core. (c) A schematic representation of the in-plane trajectory of the vortex-core motion inside the contact area. Solid lines are representatives of real results of simulation, whereas dashed lines symbolically stand for the vortex-antivortex pair nucleation, annihilation, and spin-wave emission processes. The applied current is in all the figures.
