Special Issue Information
Dear Colleagues,
Magnetic materials are differentiated on two important types, soft and hard. Soft magnetic materials are characterized by high magnetic permeability, low losses, high saturation magnetization, relatively high resistivity, and properly mechanical properties. They are widely applied as magnetic cores in transformers, in electrical generators, converters, and recently as active elements in magnetic refrigerators or heat pumps. Hard magnetic materials, on the other hand, are used in the electronic industry as magnetic recording heads, converters, sensors, in the car industry as gauges, starters or, more recently, in electric engines, in the aerospace industry as clutches, magnetrons, and magnetic bearings, in medicine as cancer cell separators and elements of artificial hearts, and as domestic devices as clocks or speakers.
The most well-known magnetic material is pure Fe; however, through many years of research, a lot of other groups have also been discovered. Today, commercially used permanent magnets are based on the RE2Fe14B phase, which is cheaper compared to SmCo5 magnets, even though the latter are of much better quality. However, some difficulties in the market of rare earth elements have forced researchers to search for magnetic material based on mixes of transition metals or transition metals–metalloids, and promising results have been achieved for MnBi and MnAl alloys. These different kinds of alloys are produced using mainly arc-melting, induction melting, melt-spinning, suction-casting or high-energy ball milling methods. Through these methods, it is possible to produce crystalline, nanocrystalline or amorphous material, which has a strong influence on the structure, microstructure, magnetic properties, and magnetization reversal processes.
This Special Issue will focus on research papers on magnetic alloys (soft and hard) based on materials with amorphous, nanocrystalline or crystalline structures. We expect novelties and original results in chemical composition, production, and studies of magnetic materials, especially their magnetization reversal processes. Manuscripts concerning modeling of magnetic properties confirmed through experimental techniques will also be considered, as well as partially glass alloys and nanostructured magnetic materials.
We invite you to submit full papers, reviews or communications to this Special Issue. In all cases, the papers must demonstrate novelty and importance to the scope.

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. 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.
