Modelling of magnetization reversal for long ferromagnetic nanotubes
نویسنده
چکیده
The theory of infinite tube magnetization reversal, formulated by Lee and Chang, has been reconsidered. For this purpose, a standard micromagnetic simulation package OOMMF was used. To account for elongated geometry of ferromagnetic nanotubes grown nowadays, an extension module has been written allowing application of periodic boundary conditions in one dimension. The results of the modelling exhibit a basic agreement with the theory. Limitations of the approach have been described and checkpoints have been discussed necessary in finite difference simulations performed for such structures.

A theory of magnetization reversal in nanowires
Magnetization reversal in a ferromagnetic nanowire which is much narrower than the exchange length is believed to be accomplished through the thermally activated growth of a spatially localized nucleus, which initially occupies a small fraction of the total volume. To date, the most detailed theoretical treatments of reversal as a field-induced but noise-activated process have focused on the ca...

Using micromagnetic modeling, we calculate numerically the magnetization reversal of soft permalloy cones of height and diameter ≤ 100nm. By varying the cone height and the base diameter in steps of 10nm and 5nm, respectively, we map the remanent states systematically. We observe reversal mechanisms with remanent configurations ranging from single domains at small diameters, through buckle stat...

We report electrical manipulation of magnetization processes in a ferromagnetic semiconductor, in which low-density carriers are responsible for the ferromagnetic interaction. The coercive force HC at which magnetization reversal occurs can be manipulated by modifying the carrier density through application of electric fields in a gated structure. Electrically assisted magnetization reversal, a...

Micromagnetic simulations of magnetization reversal were performed for magnetic nanotubes of a finite length, L, equal to 1 and 2 μm, 50 and 100 nm radii, R, and uniaxial anisotropy with "easy axis" parallel to the tube length. I.e., we considered relatively short nanotubes with the aspect ratio L/R in the range 10-40. The non-uniform curling magnetization states on both ends of the nanotubes c...
متن کاملSpin-wave theory of exchange-induced anisotropy
It is shown that exchange interactions of spins across the boundary between ferromagnetic and antiferromagnetic layers can cause a shift in the observed hysteresis loop of the ferromagnetic layer. The effect may be interpreted as a self-energy shift of each ferromagnetic spin due to emission and reabsorption of virtual antiferromagnetic spin waves. Emission of these waves by one ferromagnetic s...
