In the face of escalating modern data storage demands and the constraints of Moore's Law,
exploring spintronic solutions, particularly the devices based on magnetic skyrmions, has …

Advances in nanofabrication now allow us to manipulate magnetic material at micro-and
nanoscales. As the steps of design, modelling and simulation typically precede that of …

The existence of magnetic domains arises from the action of several interactions present in
magnetic materials, mainly exchange, anisotropy, and dipolar. This chapter deals with some …

Micron-sized magnetic platelets in the flux-closed vortex state are characterized by an in-
plane curling magnetization and a nanometer-sized perpendicularly magnetized vortex …

The theoretical foundation for a nonvolatile memory device based on magnetic vortices is
presented. We propose a realization of a vortex random-access memory (VRAM) containing …

Using the ultralow dam** NiMnSb half-Heusler alloy patterned into vortex-state magnetic
nanodots, we demonstrate a concept of nonvolatile memory controlled by the frequency. A …

Magnetic vortices are characterized by the sense of in-plane magnetization circulation and
by the polarity of the vortex core. With each having two possible states, there are four …

We report on the observation of magnetic vortex dynamics in response to rotating magnetic
fields in submicron platelets. Unlike linear fields or spin polarized currents, which excite both …

The motion of a vortex domain wall in a ferromagnetic strip of submicron width under the
influence of an external magnetic field exhibits three distinct dynamical regimes. In a viscous …

We investigate the vortex excitations induced by a spin-polarized current in a magnetic
nanopillar by means of micromagnetic simulations and analytical calculations. Damped …
