Micromagnetics and Numerical Analysis
Mathematical Models and Methods in Applied Sciences, 1997 The structure of domain walls in ferromagnetic crystals is investigated by means of micromagnetics. Moreover, the numerical integration of one-dimensional micromagnetic equations in domain walls is carried out in order to obtain approximate expressions of the energy associated to these regions.

Reduced model in thin-film micromagnetics
, 2009 The full minimization problem in micromagnetics due to Landau and Lifschitz is, from a numerical point of view, very complex. In [DeSimone et al.] a reduced model in thin-film micromagnetics has been proposed and analyzed with focus on a ...

Local minimizers in micromagnetics and related problems [PDF]
, 2002 Let $\Omega \subset{\bf R}^3$ be a smooth bounded domain and consider the energy functional ${\mathcal J}_{\varepsilon} (m; \Omega) := \int_{\Omega} \left ( \frac{1}{2 \varepsilon} |Dm|^2 + \psi(m) + \frac{1}{2} |h-m|^2 \right) dx + \frac{1}{2} \int_ ...

Computational micromagnetics with Commics [PDF]
Computer Physics Communications, 2020 We present our open-source Python module Commics for the study of the magnetization dynamics in ferromagnetic materials via micromagnetic simulations. It implements state-of-the-art unconditionally convergent finite element methods for the numerical integration of the Landau-Lifshitz-Gilbert equation.

Variational Principles of Micromagnetics Revisited [PDF]
SIAM Journal on Mathematical Analysis, 2020 We revisit the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution to the energy, which is intrinsically nonlocal. Under minimal assumptions, we establish three distinct variational principles for the stray field energy: a minimax principle

High Ms Fe16N2 thin film with Ag under layer on GaAs substrate
AIP Advances, 2016 (001) textured Fe16N2 thin film with Ag under layer is successfully grown on GaAs substrate using a facing target sputtering (FTS) system. After post annealing, chemically ordered Fe16N2 phase is formed and detected by X-ray diffraction (XRD).

AIP Advances, 2017 The heating performance of magnetic nanoparticles (MNPs) under an alternating magnetic field (AMF) is dependent on several factors. Optimizing these factors improves the heating efficiency for cancer therapy and meanwhile lowers the MNP treatment dosage.
