Reliability of AI/ML Computational Searches for Magnetic Materials: Databases, Validation, and Synthesizability
Vladimir Antropov, Subhadip Pradhan, Kirill D. Belashchenko
The rapid growth of AI/ML methods for materials discovery has increased the importance of the quality, physical completeness, and information content of computational databases. We…
Mapping metallic d-wave altermagnetism across the TiNiSi structural family
Zhen Zhang, Subhadip Pradhan, Kirill D. Belashchenko +1
The prospect of using altermagnets as switchable sources of perpendicularly polarized spin currents has intensified the search for candidate materials, yet metallic d-wave systems…
Landau theory and exchange instabilities in MnSi: A case against altermagnetism
K. D. Belashchenko
Thin-film MnSi is one of the most studied altermagnetic candidates thanks to its metallicity, demonstrated anomalous transport properties, and assumed -wave exchange spl…
Magnetoelastic coupling descriptor for high-throughput ab initio search of magnetocaloric materials
Debajit Chakraborty, Kirill D. Belashchenko, Aleksander L. Wysocki
We use Landau theory of phase transitions to design a magnetoelastic coupling descriptor that can identify magnetic materials on the brink of a first-order transition, where a stro…
Roughness-robust surface altermagnetism in antiferromagnets
K. D. Belashchenko
Surface altermagnetism extends spin splitting beyond bulk altermagnets through symmetry reduction at surfaces and interfaces. An existing classification applies to the local symmet…
Local multiferroic ordering at room temperature in collinear magnetoelectric antiferromagnets induced by flexo-Zeeman coupling
Paulina J. Prusik, Igor Veremchuk, Florin Radu +11
Spin-driven multiferroicity attracts significant interest due to its tunability and inherently strong magnetoelectric coupling. While this mechanism induces sizeable electric polar…
