Special Issue Information
Dear Colleagues,
High-efficiency motors are a very important subject. It is estimated that 40–50% of all the world’s electricity is spent on rotating electrical machines. This highlights the relevance of both soft and hard magnetic materials used in electrical motors. As a consequence of the significant demand for high-efficiency electrical steels, new types of electrical steels have been developed.
The main commercial types of hard magnets remain Nd-Fe-B of the 2:14:1 type, SmCo, alnico and barium and strontium ferrites.
However, the demand for rare-earth elements is increasing considerably due to applications in electrical vehicles and wind turbines, especially off-shore wind turbines, which consume large amount of rare-earth magnets.
Thus, alternatives for rare-earth magnets are also an interesting subject of discussion.
This Special Issue welcomes improvements on old materials, and also welcomes research developments for new alternative 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 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. Metals 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 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.
