Physical Properties of Amorphous, Nanocrystalline, High Entropy and Lanthanides-Transition Metal Alloys

Dear Colleagues,

Magnetic materials have been studied extensively for many years. The continuous development of technology enables the design of modern, functional materials in the following areas: electronics, transport, power engineering, refrigeration and medicine. Physicists and material engineers should deliver novel materials with the enhanced properties required in these disciplines. Considering the protection of the natural environment, the electromobility industry requires novel hard magnetic materials. Such novel magnets with enhanced magnetic properties are more compact and have a lower mass, which is vital with regard to a range of electric cars. The most recent studies are focused on rare-earth-free permanent magnets such as Fe-B, Fe-Ni, MnBi or novel ferrites.

Moreover, an energy-saving and environmentally-friendly cooling technique is desired; this is especially the case in the European Union, due to strict greenhouse gas emission standards. The development of the magnetic cooling sector represents one means of eliminating the use of conventional refrigeration devices. This is based on the magnetocaloric effect discovered more than one hundred years ago. For almost thirty years, many groups of scientists have produced materials such as the following: Gd₅Si₂Ge₂ alloys, La(Fe,Si)₁₃-type alloys, Heusler alloys, manganites, alloys based on the Laves phases, and Fe or Gd-based amorphous alloys. Recent studies suggest that the ideal MCM lays on the border between first- and second-order phase transition, due to the fact that it combines a relatively high magnetic entropy change and broad temperature working range. This kind of alloy possesses applicative potential in active magnetic regenerators in magnetic refrigerators or heat pumps.

This Special Issue will focus on magnetic alloys based on materials with an amorphous, nanocrystalline or crystalline structure. We welcome original results regarding the chemical composition, production, and investigation of magnetic materials, especially those with enormous magnetic properties. Manuscripts concerning the modeling of magnetic properties confirmed through experimental techniques will also be considered, as well as partially glass alloys, nanostructured or crystalline 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 be relevant to the scope of the Special Issue.

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.
