Nanocrystalline alloys represent an important class of soft magnetic materials. Their technological relevance stems from a combination of high saturation flux density, excellent permeability, and low core loss. Further improvements in magnetic performance can be achieved through careful compositional tuning and advanced processing techniques that optimize phase content and reduce grain...
The straightforward synthesis of inorganic materials, especially in the nanostructured and far-from-equilibrium states, is a great challenge despite promising developments of preparation techniques [1]. The present work provides a brief overview of the mechanochemically synthesized complex oxides. The “green” aspects of mechanochemistry are clearly illustrated by selected examples, where...
The mechanical stress strongly influences the magnetic properties of ferromagnetic materials - the magnetic hysteresis loops measured under constant stress.
In 1930 Kersten analyzed the total energy of a stressed ferromagnet and derived the analytical expression for the relative initial susceptibility that is inversely proportional to the stress for the initial part of the magnetization...
The industrial production of advanced Mn-Zn ferrites often faces unique challenges that determine its upscaling success. These range from controlling fundamental properties such as thermal expansion to meeting broader goals of innovation and sustainability. The present work aims to address key material design challenges and strategic development approaches to these goals.
One of the...
Many technological applications require low permeability of a few hundreds being constant over a wide magnetic field range. For example, this is a case of magnetic energy storage cores [1]. It is well known that magnetic anisotropy induced by stress applied during annealing can reach magnitudes up to several thousands of J/m$^3$ which is about two orders of magnitude larger than the magnetic...
Metallic glasses (MGs) are promising materials for radiation-resistant applications due to their disordered atomic structure and excellent magnetic properties. This study examines the effects of neutron irradiation (fluence up to $3\times10^{16}$ $cm^{−2}$) on Fe-based metallic glasses using Mössbauer spectroscopy (MS) and X-ray diffraction (XRD).
XRD analysis, particularly total scattering...
