The methodology for adapting a standard micromagnetic code to run on graphics processing units (GPUs) and exploit the potential for parallel calculations of this platform is discussed. GPMagnet, a general purpose finite-difference GPU-based micromagnetic tool, is used as an example. Speed-up factors of two orders of magnitude can be achieved with GPMagnet with respect to a serial code. This allows for running extensive simulations, nearly inaccessible with a standard micromagnetic solver, at reasonable computational times.read more

Current-driven excitation of magnetic multilayers
TL;DR: In this paper, a new mechanism was proposed for exciting the magnetic state of a ferromagnet, where a transfer of vectorial spin accompanied an electric current flowing perpendicular to two parallel magnetic films connected by a normal metallic spacer.

Emission of spin waves by a magnetic multilayer traversed by a current.
TL;DR: In this paper, the interaction between spin waves and itinerant electrons is considerably enhanced in the vicinity of an interface between normal and ferromagnetic layers in metallic thin films, leading to a local increase of the Gilbert damping parameter which characterizes spin dynamics.

Thermal Fluctuations of a Single-Domain Particle
TL;DR: In this article, the Langevin equation of the Fokker-planck partial differential equation is replaced by a random-field term, which can be avoided by using the fluctuation-dissipation theorem.
