Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Effect of Indirect Exchange Interaction on Ferromagnetic Resonance in Magnetic Nanogranular Films [PDF]

Журнал нано- та електронної фізики, 2014
The effect of the non-magnetic matrix conducting properties on the ferromagnetic resonance of the ensembles of ferromagnetic metal nanogranules in magnetic nanogranular films with different types of non-magnetic matrix (metal and dielectric) was ...

Intensity enhancement of ferromagnetic resonance modes in exchange coupled magnetic multilayers

New Journal of Physics, 2020
In this work, the ferromagnetic resonance characteristics of a NiFeCu/Non-magnetic(NM)/NiFe/NM/CoFe/NM/Co multilayer is studied from a theoretical point of view, and comparisons with the ferromagnetic resonance of a NiFe/NM/CoFe magnetic bilayer are ...

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Resonance behavior of embedded and freestanding microscale ferromagnets

Scientific Reports, 2022
The ferromagnetic resonance of a disordered A2 Fe60Al40 ferromagnetic stripe, of dimensions 5 µm × 1 µm × 32 nm, has been observed in two vastly differing surroundings: in the first case, the ferromagnetic region was surrounded by ordered B2 Fe60Al40 ...

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Ferromagnetic Resonance Characterization of Nano-FePt by Electron Spin Resonance

Journal of Spectroscopy, 2013
Electron spin resonance (ESR) measurements at room temperature and X-band microwave frequency were performed on highly crystalline FePt system thin films. Fairly high DC static magnetic field absorption of about 300 mT was observed in these films.

Lumped circuit model for inductive antenna spin-wave transducers

Scientific Reports, 2022
We derive a lumped circuit model for inductive antenna spin-wave transducers in the vicinity of a ferromagnetic medium. The model considers the antenna’s Ohmic resistance, its inductance, as well as the additional inductance due to the excitation of ...
