Magnetic Studies of Complex Alloys

Dear Colleagues,

The research on complex alloys is still increasing. The term complex alloys denotes a broad family of binary or multinary compounds consisting of, e.g., either metallic elements or mixtures of metals to which metalloids, rare earth elements, or chalcogenides are added. Their crystal structure is based on very large elementary unit cells. The use of the term complex and the discussion of complexity are rapidly increasing in last years. Magnetic properties of such complex structures could be interesting. These alloys could be used for different purposes, like in the rapidly developing field of magnetocaloric properties. The main aim is to find new materials that are eco-friendly and substitute the gases used in conventional refrigerators in the vicinity of room temperature. Finding new progressive materials with these effects is important to meet the needs of space research. A further example is finding materials applicable in information technologies, where magnetoresistance is crucial.

The control of the magnetic state is essential in engineering. The magnetic state can often be tuned using a chemical method employing an interstitial site or atomic substitution. High-entropy alloys are state-of-the-art complex alloys materials. Control of the magnetic state following the high-entropy alloy concept might lead to a multifunctional material. Control of the magnetic state by external fields is essential, as is influence of properties like the optical wave or the electric field. Associated with the development of nanotechnology, the fields of spintronics and nanostructured magnetic materials also offer many new fascinating magnetic phenomena. 

The goal of this Special Issue is to collect articles mainly concerning the frontiers of research on the magnetic properties of complex alloys. Both experimental and theoretical approaches are encouraged, and review articles are welcome. Research articles on the development of measurement and analysis methods to assess these materials are welcome.

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.
