Special Issue Information

Dear Colleagues,

The Special Issue “Advances in Magnetic Materials and Applications” aims to exhibit the latest studies and developments in the design, synthesis, characterization, and application of magnetic materials across diverse fields. Magnetic materials play a crucial role in science and engineering, with applications ranging from data storage, spintronics, and sensing technologies to energy conversion and biomedical devices. This Special Issue seeks to bring together contributions that address both fundamental aspects (such as magnetic structure, exchange interactions, and magneto-transport phenomena) and applied innovations that can be harnessed for potential functional devices. Topics of interest include but are not limited to the following: soft and hard magnetic materials, magnetic nanostructures, multifunctional and composite magnets, magnetic semiconductors, and hybrid systems. Emphasis is also placed on emerging fabrication techniques, advanced characterization methods, theoretical modeling, and simulations that enhance the identification of magnetism at scales of different lengths. Through integrating experimental, computational, and application-driven perspectives, this Special Issue will serve as a platform for scientists to share innovations, identify challenges, and inspire future directions in magnetic materials science, which will pave the way towards new technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The recycling of NdFeB magnets is essential to reduce reliance on critical rare earth elements and mitigate the environmental burden of virgin magnet production. Hydrogen Processing of Magnetic Scrap (HPMS) offers an efficient method to extract magnet powders from end-of-life (EOL) products, yet oxidation and microstructural degradation during powder preparation limit the magnetic performance of recycled magnets. In this work, rapid Radiation-Assisted Sintering (RAS) was systematically evaluated for the first time as a consolidation route for HPMS-derived powders. Magnets prepared via RAS exhibited performance comparable to those obtained by conventional sintering. When oxygen uptake during milling was prevented, the addition of 1 wt.% NdH3 to the already oxygen-burdened recycled powder improved the intrinsic coercivity and squareness of the demagnetization curve. The best-performing samples achieved Br = 1.18 T, (BH)max = 263 kJ/m3, and Hci = 742 kA/m at 100 °C, surpassing the properties of the original EOL magnets. Furthermore, the study revealed that, when the HPMS powder fragments preferentially break along grain boundaries, the resulting near-equilibrium powder particles exhibit limited growth, thereby restraining grain coarsening. These findings highlight the strong potential of RAS for more energy-efficient magnet-to-magnet recycling and provide new insight into optimizing HPMS powder processing to achieve enhanced magnetic performance.
