Switching phenomena in magnetic vortex dynamics
Yuri B. Gaididei, Volodymyr P. Kravchuk, Franz G. Mertens +1
A magnetic nanoparticle in a vortex state is a promising candidate for the information storage. One bit of information corresponds to the upward or downward magnetization of the vo…
Effective anisotropy of thin nanomagnets: beyond the surface anisotropy approach
Jean-Guy Caputo, Yuri Gaididei, Volodymyr P. Kravchuk +2
We study the effective anisotropy induced in thin nanomagnets by the nonlocal demagnetization field (dipole-dipole interaction). Assuming a magnetization independent of the thickne…
Controlled vortex core switching in a magnetic nanodisk by a rotating field
Volodymyr P. Kravchuk, Denis D. Sheka, Yuri Gaididei +1
The switching process of the vortex core in a Permalloy nanodisk affected by a rotating magnetic field is studied theoretically. A detailed description of magnetization dynamics is…
Equilibrium magnetisation structures in ferromagnetic nanorings
Volodymyr P. Kravchuk, Denis D. Sheka, Yuri B. Gaididei
The ground state of the ring-shape magnetic nanoparticle is studied. Depending on the geometrical and magnetic parameters of the nanoring, there exist different magnetisation confi…
