Special Issue Information

Dear Colleagues,

Magnetic alloys and compounds constitute one of the most prominent classes of materials with many present and emerging applications, including permanent magnets, soft magnets, magnetic recording media, sensors, magnetic refrigerators, and spin-transport-based electronics. Some magnetic alloys exhibit novel phenomena, such as half-metallic and spin-gapless semiconducting properties, colossal magnetoresistive effect, giant magnetocaloric effect, magnetoelastic effect and non-collinear magnetic texture. One attractive class of materials exhibiting these novel phenomena are Heusler alloys. The discovery of materials exhibiting such properties has been possible due to recent advances in theoretical understanding, computational ability and materials processing.

This Special Issue is expected to collect articles reporting original results on the fabrication, characterization, experimental investigation, theoretical understanding and practical application of magnetic alloys exhibiting some of above-mentioned novel phenomena, as well as review papers about particular topics.

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.

In this work, the iron oxide (Fe2O3) nanoflakes on carbon cloth (Fe2O3@CC) were triumphantly prepared and served as the electrode of supercapacitors. By applying an external magnetic field, we first find that the magnetic field could suppress the polarization phenomenon of electrochemical performance. Then, the influences of the mono-/bi-valent cations on the electrochemical properties of the Fe2O3@CC were investigated under a large external magnetic field (1 T) in this work. The chemical valences of the cations in the aqueous electrolytes (LiNO3 and Ca(NO3)2) have almost no influences on the specific capacitance at different scan rates. As one of important parameters to describe the electrochemical properties, the working potential window of the Fe2O3@CC electrode was also investigated in this work. The broad potential window in room-temperature molten salt (LiTFSI + LiBETI (LiN(SO2CF3)2 + LiN(SO2C2F5)2)) has been obtained and reached 1.2 V, which is higher than that of the traditional aqueous electrolyte (~0.9 V).
