Nonreciprocal Spin Waves in Nanoscale Hybrid Néel–Bloch–Néel Domain Walls Detected by Scanning X‐Ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers

open access: yesAdvanced Materials, EarlyView.
Using scanning transmission X‐ray microscopy, nonreciprocal spin‐wave behavior is revealed in real space in Fe/Gd multilayers with perpendicular magnetic anisotropy, highlighting their functionality for magnonic logic circuits operating at GHz frequencies.

Semi-strong split domination in graphs [PDF]

open access: yesTransactions on Combinatorics, 2014
Given a graph $G = (V,E)$, a dominating set $D subseteq V$ is called a semi-strong split dominating set of $G$ if $|V setminus D| geq 1$ and the maximum degree of the subgraph induced by $V setminus D$ is 1.

On the uniqueness of d-vertex magic constant

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Let G = (V,E) be a graph of order n and let D ⊆ {0, 1, 2, 3, . . .}. For v ∈ V, let ND(v) = {u ∈ V : d(u, v) ∈ D}. The graph G is said to be D-vertex magic if there exists a bijection f : V (G) → {1, 2, . . .

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

On the nuclear trace of Fourier integral operators

open access: yesRevista Integración, 2019
In this paper we characterise the r-nuclearity of Fourier integral operators on Lebesgue spaces. Fourier integral operators will be considered in Rn, the discrete group Zn, the n-dimensional torus and symmetric spaces (compact homogeneous manifolds).

A Triple of Heavy Subgraphs Ensuring Pancyclicity of 2-Connected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A graph G on n vertices is said to be pancyclic if it contains cycles of all lengths k for k ∈ {3, . . . , n}. A vertex v ∈ V (G) is called super-heavy if the number of its neighbours in G is at least (n+1)/2.
