C16 Phase High Entropy Borides With High Magnetic Anisotropy
Advanced Materials, EarlyView.Rare‐earth‐free C16‐phase high entropy boride thin films exhibit enhanced magnetic anisotropy with coercivities surpassing their binary and ternary counterparts. Combinatorial synthesis of (Fe‐Co‐Ni‐Mn)2B films combined with density functional theory enables mapping of the magnetic properties across the composition space, revealing high entropy ...

Covariance within Random Integer Compositions
, 2020 Fix a positive integer $N$. Select an additive composition $ $ of $N$ uniformly out of $2^{N-1}$ possibilities. The interplay between the number of parts in $ $ and the maximum part in $ $ is our focus. It is not surprising that correlations $ (N)$ between these quantities are negative; we earlier gave inconclusive evidence that $\lim_{N \to \infty}

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings
Advanced Materials, EarlyView.This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external
