Magnetization reversals in a disk-shaped small magnet with an interface
R. L. Silva, A. R. Pereira, W. A. Moura-Melo
We consider a nanodisk possessing two coupled materials with different ferromagnetic exchange constant. The common border line of the two media passes at the disk center dividing t…
Predicted defect induced vortex core switching in thin magnetic nanodisks
R. L. Silva, A. R. Pereira, W. A. Moura-Melo +4
We investigate the influence of artificial defects (small holes) inserted into magnetic nanodisks on the vortex core dynamics. One and two holes (antidots) are considered. In gener…
A model for structural defects in nanomagnets
F. A. Apolonio, W. A. Moura-Melo, F. P. Crisafulli +2
A model for describing structural pointlike defects in nanoscaled ferromagnetic materials is presented. Its details are explicitly developed whenever interacting with a vortex-like…
