Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States
Advanced Functional Materials, EarlyView.The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

A note on the growth factor in Gaussian elimination for generalized Higham matrices
, 2013 The Higham matrix is a complex symmetric matrix A=B+iC, where both B and C are real, symmetric and positive definite and $\mathrm{i}=\sqrt{-1}$ is the imaginary unit. For any Higham matrix A, Ikramov et al.

On minimizing the largest eigenvalue of a symmetric matrix
Linear Algebra and its Applications, 1995 This paper concerns the (nondifferentiable) optimization problem (1) \(\lambda^* = \inf_{x \in \mathbb{R}^ m} \lambda_ 1 (x)\), where \(\lambda_ 1 (x)\) are the largest eigenvalues of \(A(x) = A_ 0 + \sum^ m_{j=1} x_ jA_ j\) and the \(A_ j\) are symmetric. It gives a sufficient condition on \(x\) to satisfy \(\lambda_ 1 (x) - \varepsilon \leq \lambda^*

Advanced Functional Materials, EarlyView.This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

High‐Entropy Magnetism of Murunskite
Advanced Functional Materials, EarlyView.The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

An approximate solution for a system with a symmetric matrix
Computers & Mathematics with Applications, 1997 This paper deals with a discrete approximation for the solution of the boundary value problem for an ordinary differential equation (unusually formulated). Using methods of the Numerov's type a system of equations is obtained. The matrix of this large system of equations is reformulated as the product of two bounded matrices for the purpose of ...

Advanced Functional Materials, EarlyView.The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies
Advanced Functional Materials, EarlyView.This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.
