Large spin splitting at ferromagnetic surfaces of bulk antiferromagnets
William A. Schaarman, Sophie F. Weber
We use density functional theory and model Hamiltonians to reveal large spin splitting of bands localized at ferromagnetic surfaces of bulk antiferromagnets (AFMs). There is great…

Deterministic domain selection of antiferromagnets via magnetic fields
Sophie F. Weber, Veronika Sunko
Antiferromagnets (AFMs) hold promise for applications in digital logic. However, switching AFM domains is challenging, as magnetic fields do not couple to the bulk antiferromagneti…

Local Magnetoelectric Effects as a Predictor of Surface Magnetic Order
Sophie F. Weber, Andrea Urru, Nicola A. Spaldin
We use symmetry analysis and density functional theory to show that changes in magnetic order at a surface with respect to magnetic order in the bulk can be generically determined…
