New Horizons in Antiferromagnetic Spintronics: Exotic Ground States and Device Prospects

Dear Colleagues,

Antiferromagnetic materials, by virtue of their vanishing stray field and ultrafast dynamics, hold exceptional promise for next‐generation high performance spintronic devices. Nevertheless, the very feature that makes them attractive—zero net magnetization—also complicates the manipulation and detection of their spin states. Over the past decades, the discovery of various compensated spin textures, including non‐collinear antiferromagnets, skyrmion lattices, helical spin orders and altermagnets, has significantly enriched our understanding of fundamental spin and topological physics. The designed construction of these exotic ground states via techniques like magnetic intercalation, chemical substitution, epitaxial growth, and van der Waals heterostructure assembly, have, therefore, opened fresh avenues for both writing and reading spin information in antiferromagnetic systems.

This Special Issue aims to highlight recent advances in the design, understanding, and manipulation of novel antiferromagnetic orders. Research areas may include (but are not limited to) the following:

1. Synthesis and characterizations of antiferromagnetic materials with nontrivial spin textures;
2. Modelling phase transition mechanisms and dynamic behaviours of exotic spin textures;
3. Transport phenomena arising from the antiferromagnetic ground states such as anomalous/spin Hall effects, magnetoelectric effects, thermospin effects, etc.;
4. Spin torque switching and ultrafast control of antiferromagnetic order;
5. Proof-of-concept spintronic devices based on antiferromagnetic materials;
6. Dynamics of synthetic antiferromagnetic spin textures;
7. Comparison between antiferromagnetic and altermagnetic material systems.

We look forward to receiving your contributions.

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.
