Special Issue Information

Dear Colleagues,

The Special Issue on magnetism and magnetic properties of ferromagnetic amorphous alloys focuses onthe characterization, modeling and applications of amorphous alloys. Amorphous (and nanocrystalline) alloys have substantially advanced magnetic, magnetostrictive and magnetotransport properties. The Special Issue addresses original studies related to materials, simulations, characterization and technological applications, namely:

  • Magnetic materials, with an emphasis on magnetostrictive, magnetoelectric and ultrasoft magnetic transition alloys, especially medium- to high-entropy amorphous alloys;
  • Characterization of these amorphous alloys: magnetic characterization, namely magnetic, magnetostrictive, magneto-transport, magnetoelectric, magnetocaloric and other magnetic properties;
  • Structural characterization of these amorphous alloys, using scanning and transmission electron microscopy, X-ray diffraction, XPS, and AFM-MFM-STM surface characterization;
  • Correlation of magnetic and structural properties, based on micro-magnetics modeling, finite elements analysis, density function theory-based magnetic modeling, and other simulation techniques;
  • Technological applications in the field of (energy, industrial, security, biological, etc.) sensors, actuators, energy harvesting systems, automated systems and other technological applications.

Papers submitted for publication are subject of peer review process. The Special Issue aims at being a milestone in the technological applications of magnetism.

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. Magnetism is an international peer-reviewed open access quarterly 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 1000 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.

Theoretical calculations of the temperature-dependent magnetization in FeGd alloys were done with the use of Heisenberg-type atomistic spin Hamiltonian and Monte Carlo algorithms. The random allocation of atoms in the desired crystal structure was used for simulations of magnetically amorphous alloys. Performed calculations for the two different crystal structures have shown an important role of coordination number on the observed critical temperature and compensation point. Moreover, the value of the exchange interaction between Fe and Gd sublattices plays a key role in the simulations—an increase in the Fe–Gd exchange constant provides an increase in critical temperature for each concentration of elements, which explains the higher temperature stabilization of Gd moments. It was shown that obtained temperature-dependent magnetization behavior is consistent with experimental observations, which confirms the applicability of the atomic model used to study FeGd or other magnetic alloy structures.
