Long time behaviour of a stochastic nano particle
Pierre Etoré, Stéphane Labbé, Jérôme Lelong
In this article, we are interested in the behaviour of a single ferromagnetic mono-domain particle submitted to an external field with a stochastic perturbation. This model is the…
Static ferromagnetic materials: from the microscopic to the mesoscopic scale
Brigitte Bidégaray-Fesquet, Quentin Jouet, Stéphane Labbé
Thanks to averaging processes and Gamma-convergence techniques, we are able to link a microscopic description of ferromagnetic materials based on spin lattices and their mesoscopic…
Control of travelling walls in a ferromagnetic nanowire
Gilles Carbou, Stéphane Labbé, Emmanuel Trélat
We investigate the problem of controlling the magnetic moment in a ferromagnetic nanowire submitted to an external magnetic field in the direction of the nanowire. The system is mo…
Stability for Walls in Ferromagnetic Nanowire
Gilles Carbou, Stéphane Labbé
We study the stability of travelling wall profiles for a one dimensional model of ferromagnetic nanowire submitted to an exterior magnetic field. We prove that these profiles are a…
