Special Issue Information
Dear Colleagues,
Permanent ferrite magnet materials, especially M-type hexaferrites such as strontium ferrite and barium ferrite, remain among the most widely used permanent magnetic materials because of their low cost, abundant raw materials, excellent chemical stability, corrosion resistance, and reliable performance under demanding service conditions. Although rare-earth permanent magnets possess higher maximum energy products, ferrite magnets continue to play an irreplaceable role in large-scale applications, including motors, sensors, loudspeakers, automotive components, microwave devices, and energy-related technologies. With the increasing demand for rare-earth-saving, sustainable, and cost-effective magnetic materials, the fundamental understanding and performance optimization of permanent ferrites have become increasingly important.
This Special Issue, “Permanent Ferrite Magnet Materials: Fundamentals, Advances and Applications”, aims to provide a platform for recent progress in the chemistry, physics, processing, characterization, and application of permanent ferrite magnets. Particular attention will be given to composition design, ion substitution, lattice-site occupancy regulation, magnetocrystalline anisotropy, defect chemistry, crystallographic texture, grain-boundary engineering, coercivity mechanisms, and magnetic domain behavior. Contributions dealing with advanced synthesis routes, ceramic processing, single-crystal growth, microstructure control, and scalable manufacturing are also highly encouraged.
In addition, this Special Issue welcomes studies that combine advanced characterization, theoretical calculations, micromagnetic simulations, high-throughput experimentation, and machine-learning-assisted materials design to clarify structure–property relationships and accelerate the discovery of high-performance ferrite magnets. Research on high-frequency, high-temperature, motor, sensor, and microwave applications is also within the scope. Both original research articles and review papers are welcome. Through this collection, we aim to promote a deeper understanding of permanent ferrite magnet materials, bridge fundamental magnetochemistry and practical engineering, and support the development of next-generation rare-earth-lean or rare-earth-free permanent magnetic materials.

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. Magnetochemistry is an international peer-reviewed open access monthly 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 2200 CHF (Swiss Francs).
