Curvature effects in statics and dynamics of a thin magnetic shell
Yuri Gaididei, Volodymyr P. Kravchuk, Denis D. Sheka
Equations of the magnetization dynamics are derived for an arbitrary curved 2D surface. General static solutions are obtained in the limit of a strong anisotropy of both signs (eas…
Effects of Surface Anisotropy on Magnetic Vortex Core
Oleksandr V. Pylypovskyi, Denis D. Sheka, Volodymyr P. Kravchuk +1
The vortex core shape in the three dimensional Heisenberg magnet is essentially influenced by a surface anisotropy. We predict that depending of the surface anisotropy type there a…
Resonantly exited precession motion of three-dimensional vortex core in magnetic nanospheres
Sang-Koog Kim, Myoung-Woo Yoo, Jehyun Lee +5
We found resonantly excited precession motions of a three-dimensional vortex core in soft magnetic nanospheres and controllable precession frequency with the sphere diameter 2R, as…
Periodic magnetic structures generated by spin-polarized currents in nanostripes
Oleksii M. Volkov, Volodymyr P. Kravchuk, Denis D. Sheka +2
The influence of a spin-polarized current on long ferromagnetic nanostripes is studied numerically. The current flows perpendicularly to the stripe. The study is based on the Landa…
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…
Periodic magnetization structures generated by transverse spin-current in magnetic nanowires
Volodymyr P. Kravchuk, Oleksii M. Volkov, Denis D. Sheka +1
Magnetization behavior of long nanowires with square cross-section under influence of strong perpendicular spin-polarized current is studied theoretically. The study is based on La…
