Special Issue Information

Dear Colleagues,

Magnetic materials play an important role in developing improved devices for spintronics and similar applications. While hard disk drives and magnetic field sensors have been commercially available for a long time, most spintronics elements still necessitate further research and development to achieve reliable and reproducible devices.

In these spintronics devices, different physical effects are used, such as GMR or TMR, to realize magnetic tunnel junctions, spin valves, diodes, logic gates, memory cells, etc. They can be applied for logic operations, information processing and storage, neuromorphic computing, or sensors.

Amongst the materials with special physical effects that may be used in spintronics devices are, e.g., systems with Dzyaloshinskii-Moriya interactions, exotic magnetic states, magnetization texture, periodic magnonic systems, and magnonic crystals. In addition to experimental investigations, computational methods are also of interest.

This Special Issue is open for the most recent research and developments in spintronics devices, as well as comprehensive reviews of the recent state of this emerging technology.

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. Micromachines 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 2100 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.

Heusler compounds and alloys constitute a burgeoning class of materials with exceptional properties, holding immense promise for advanced technologies. Electronic band structure calculations are instrumental in driving research in this field. Nowotny–Juza compounds are similar to Semi-Heusler compounds containing one instead of two transition metal atoms in their chemical formula. Recently, they have been widely referred to as “p0-d or d0-d Semi-Heusler compounds”. Building upon our previous studies on p0-d or d0-d Semi-Heusler compounds featuring Li or K, we now explore a new class of d0-d compounds incorporating alkaline earth metals and more specifically Mg which is well-known to occupy all possible sites in Heusler compounds. These compounds, with the general formula MgZ(Ga, Ge, or As), where Z is a transition metal, are investigated for their structural, electronic, and magnetic properties, specifically within the context of the three possible C1b structures including also the effect of tetragonalization which is shown not to affect the equilibrium cubic type. Our findings demonstrate that a significant number of these compounds exhibit magnetic behavior, with several displaying half-metallicity, making them highly attractive for spintronic applications. This research provides a crucial foundation for future experimental investigations into these promising materials. Full article
