Special Issue Information

Dear Colleagues,

In the field of nanometer-sized magnetic materials, there is continuous research effort to shift the paradigm toward a variety of technological applications that use novel properties and phenomena linked with the downsizing of the magnetic entity, such as magnetic nanoparticles, nanograins, magnetic dots, magnetic molecules, or monolayers. Steady and continuous advancement in the field of nanosized magnetic materials is overwhelming and has generally been achieved as a response to a specific application, property, or technological need. As research in this field is predominantly application- and property-oriented, for this Special Issue, we welcome original contributions that present the development of nanosized magnetic materials, specifically tailored for applications in a diversity of disciplines, such as, but not limited to, solid-state physics, nanoelectronics, biology, metallurgical engineering, materials science, solid-state chemistry, electrochemistry, nanosciences, and so on. We also welcome interdisciplinary contributions, as nanosized magnetic materials have a tremendous range of applicability for almost every aspect of contemporary technology: artificial intelligence, machine learning, automotive, sensoring, photonics, renewable energy, biomedical applications, high-tech, information and communications technologies, environment, space and security applications, power generation and many others. Together with the Editorial Board, we will maintain an expedited article processing procedure, including a competent, transparent, and fast peer review, to ensure the fastest dissemination of your research results.

Magnetic nanoscale materials exhibiting the L10 tetragonal phase such as FePt or ternary alloys derived from FePt show most promising magnetic properties as a novel class of rare earth free permanent magnets with high operating temperature. A granular alloy derived from binary FePt with low Pt content and the addition of Mn with the nominal composition Fe57Mn8Pt35 has been synthesized in the shape of melt-spun ribbons and subsequently annealed at 600 °C and 700 °C for promoting the formation of single phase, L10 tetragonal, hard magnetic phase. Proton-induced X-ray emission spectroscopy PIXE has been utilized for checking the compositional effect of Mn addition. Structural properties were analyzed using X-ray diffraction and diffractograms were analyzed using full profile Rietveld-type analysis with MAUD (Materials Analysis Using Diffraction) software. By using temperature-dependent synchrotron X-ray diffraction, the disorder–order phase transformation and the stability of the hard magnetic L10 phase were monitored over a large temperature range (50–800 °C). A large interval of structural stability of the L10 phase was observed and this stability was interpreted in terms of higher ordering of the L10 phase promoted by the Mn addition. It was moreover found that both crystal growth and unit cell expansion are inhibited, up to the highest temperature investigated (800 °C), proving thus that the Mn addition stabilizes the formed L10 structure further. Magnetic hysteresis loops confirmed structural data, revealing a strong coercive field for a sample wherein single phase, hard, magnetic tetragonal L10 exists. These findings open good perspectives for use as nanocomposite, rare earth free magnets, working in extreme operation conditions. Full article
