This paper presents an efficient and simple approach of implementing the Landau-Lifshitz-Gilbert (LLG) equation of magnetisation motion within the Finite-difference Time-domain (FDTD) method. This combined electromagnetic-micromagnetic simulation technique is particularly important for modeling electromagnetic interaction with lossy magnetic material in the presence of current and magnetic sour...

The parameters of a linear block code over the finite field Fq of length n, dimension k and minimum distance d will be denoted by [n, k, d]q or [n, k, d]. The quotient k/n is called the information rate and denoted by R = k/n and the relative minimum distance d/n is denoted by δ. A sequence of codes (Cm|m ∈ N) with parameters [nm, km, dm] over a fixed finite field Fq is called asymptotically go...

The paper discusses some ways to strengthen (nonasymptotically) the Gilbert–Varshamov bound for linear codes. The unifying idea is to study a certain graph constructed on vectors of low weight in the cosets of the code, which we call the Varshamov graph. Various simple estimates of the number of its connected components account for better lower bounds on the minimum distance of codes, some of t...

Material for an analysis of the pathogenesis and course of acute peripheral arterial ocelusion was provided by patients with acute arterial occlusion in a lower extremity, special arterial injection studies of amputated limbs, arteriograms performed on cadavers, and data from nai experimental investigation of acute femoral artery embolism in dogs. This correlative study offers a basis for the e...

We establish a machine learning model for the prediction of magnetization dynamics as function external field described by Landau-Lifschitz-Gilbert equation, partial differential equation motion in micromagnetism.

Within the framework of the Landau-Lifshitz-Gilbert equation, using permalloy parameters, we study the statics and dynamics of flat circular magnetic nano-structures with an in-plane magnetic vortex configuration, putting particular emphasis on the vorticity of the magnetic state and on the (perpendicular) polarisation of the vortex center, which may be shifted with respect to the center of the...

In this paper, we study the domain wall motion induced by vertical current flow in asymmetric magnetic tunnel junctions. The free layer is mainly dictated current-induced field-like torque acting on it. We show that as increase MTJ asymmetry, considering dissimilar ferromagnetic contacts, a linear-in-voltage behavior accompanied an enhancement displacement efficiency and higher degree of bidire...
