Calculation of coercivity of magnetic nanostructures at finite temperatures
, 2011 We report a finite temperature micromagnetic method (FTM) that allows for the calculation of the coercive field of arbitrary shaped magnetic nanostructures at time scales of nanoseconds to years.

THIN LAYERS IN MICROMAGNETISM [PDF]
Mathematical Models and Methods in Applied Sciences, 2001 In this paper we study the solutions of micromagnetism equation in thin domain both in the stationary and in the time-dependent case. We prove that the magnetic field induced by the magnetisation behaves like the projection of the magnetic moment on the normal to the domain, both for a flat and a non-flat domain.

A self-consistent spin-diffusion model for micromagnetics
Scientific Reports, 2016 We propose a three-dimensional micromagnetic model that dynamically solves the Landau-Lifshitz-Gilbert equation coupled to the full spin-diffusion equation.

Stochastic thermodynamics of micromagnetics
Journal of Statistical Mechanics: Theory and ExperimentAbstract In this work, we study the stochastic thermodynamics of micro-magnetic systems. We first formulate the stochastic dynamics of micro-magnetic systems by incorporating noises into the Landau–Lifshitz (LL) equation, which describes the irreversible and deterministic dynamics of magnetic moments. The resulting stochastic LL equation

A Two-Dimensional Landau-Lifshitz Model in Studying Thin Film Micromagnetics
Abstract and Applied Analysis, 2009 The paper is concerned with a two-dimensional Landau-Lifshitz equation which was first raised by A. DeSimone and F. Otto, and so fourth, when studying thin film micromagnetics.

Time Average in Micromagnetism
Journal of Differential Equations, 1998 The authors consider a ferromagnetic material whose properties are defined by Maxwell's equations and a nonlinear Landau-Lifschitz equation and show that weak solutions exist. This is done by solving a relaxed system by the Galerkin process and allowing the parameter to tend to zero.

Homogenization of micromagnetics large bodies [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2004 The author considers an homogenization problem for the micromagnetic energy functional. In particular the integral representation for the homgenized limit of the family of energies \[ \mathcal{E}(m) = \int_\Omega \varphi \biggl(x,\frac{x}{\varepsilon},m(x)\biggr)\,dx - \int_\Omega h_\varepsilon(x)m(x)\, dx + \frac{1}{2} \int_{\mathbb R^3}| \nabla u| ^2

Deposition and spin polarization study of Fe4N thin films with (111) orientation
AIP Advances, 2017 We have successfully deposited Fe4N thin films with (111) out-of-plane orientation on thermally oxidized Si substrates using a facing-target-sputtering system.
