Magnetic Vortex Dynamics on a Spherical Cap
Mykola I. Sloika, Yuri Gaididei, Volodymyr P. Kravchuk +3
By tailoring geometrical properties of magnetic nanocap structures, new possibilities appear to control its magnetic properties, such as the dynamics of magnetic vortices. Here, we…
Impact of curvature-induced Dzyaloshinskii-Moriya interaction on magnetic vortex texture in spherical caps
Mykola I. Sloika, Yuri Gaididei, Volodymyr P. Kravchuk +3
Geometric curvature of nanoscale magnetic shells brings about curvature-induced anisotropy and Dzyaloshinskii-Moriya interaction (DMI). Here, we derive equations to describe the pr…
Geometry induced phase transitions in magnetic spherical shell
Mykola I. Sloika, Denis D. Sheka, Volodymyr P. Kravchuk +2
Equilibrium magnetization states in thin spherical shells of a magnetically soft ferromagnet are determined by the competition between two interactions: (i) The local exchange inte…
Curvature induced chirality symmetry breaking in vortex core switching phenomena
Mykola I. Sloika, Volodymyr P. Kravchuk, Denis D. Sheka +1
The interplay between magnetic vortex polarity, chirality and the curvature of the underlying surface results in a dependence of the vortex polarity switching efficiency on the vor…
Equilibrium states of soft magnetic hemispherical shell
Denis D. Sheka, Volodymyr P. Kravchuk, Mykola I. Sloika +1
The ground state of hemispherical permalloy magnetic shell is studied. There exist two magnetic phases: the onion state and the vortex one. The phase diagram is systematically anal…
