Special Issue Information

Dear Colleagues,

Rare earth free permanent magnets are being actively studied for their potential as a future class of magnetic materials, capable of operating at higher temperatures and in challenging corrosion environments, such as renewable energy applications. Of these classes, novel magnets without rare earth components show promise, as they are cost-effective and have interesting magnetic properties. Sustained efforts are being made nowadays in the search for new classes of magnets, motivated by the continuous depletion of rare earth oxide resources and the need for improved magnetic parameters, especially for high-temperature applications. Indeed, rare-earth-free magnets can operate under extreme conditions such as high temperatures and corrosive media, which are the milieu of the operation of motors in wind turbines subjected to strong variations in temperature and humidity. Various possible rare-earth-free magnets have been proposed and largely investigated, using compounds derived from the binary systems FePt, MnAl, MnBi, MnGa, etc. What is common for all these different systems is the fact that they all may exhibit, under certain conditions, the formation of the tetragonal L10 phase, which has been shown to present large magnetocrystalline anisotropy and high coercivity.

The aim of this Special Issue is to investigate the crystal structures responsible for the enhanced magnetic performances of rare-earth-free magnetic materials.

This Special Issue will address all the challenges involved in developing optimized crystal structures in novel rare-earth-free nanocomposite magnets, including, but not limited to, the following topics:

  • Theory and modelling;
  • Synthesis challenges and microstructure optimization;
  • Magnetic phase coexistence and phase stability with temperature;
  • Hard–soft exchange coupling in multiphase magnetic nanocomposites;
  • Optimization of magnetic performances in rare-earth-free nanocomposite magnets;
  • Magnetic performances in extreme conditions of operation.

Manuscript Submission Information

Manuscripts should be submitted online at 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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
