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…
Piezomagnetic Switching of Nonvolatile Antiferromagnetic States
Xilai Bao, Oleksandr V. Pylypovskyi, Huali Yang +17
Prospective spintronic memory and logic devices will benefit from the negligible stray field and ultrafast magnetic dynamics inherent to antiferromagnets [1]. However, realizing is…
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…
Emergent surface multiferroicity
Sayantika Bhowal, Andrea Urru, Sophie F. Weber +1
We show that the surface of a centrosymmetric, collinear, compensated antiferromagnet, which hosts bulk ferroically ordered magnetic octupoles, exhibits a linear magnetoelectric ef…
First-principles study of structural, electronic and magnetic properties at the \ce{(0001)Cr2O3-(111)Pt} interface
Marlies Reher, Nicola A. Spaldin, Sophie F. Weber
We perform first-principles density functional calculations to elucidate structural, electronic and magnetic properties at the interface of \ce{(0001)Cr2O3-(111)Pt} bilayers. This…
