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…
Synthetic Persona Pretraining: Alignment from Token Zero
Julian Minder, Viktor Moskvoretskii, Raghav Singhal +12
As language-model-based AI is increasingly deployed in autonomous settings, aligning its goals and values with those of humans becomes critical. Today, alignment, and the assistant…
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…
Deterministic Electrical Switching in Altermagnets via Surface Antisymmetry Groups
K. D. Belashchenko
A surface antisymmetry group framework is developed to establish design rules for deterministic electrical switching of the Néel vector in a film of a collinear bipartite antiferr…
