Ferroelectric -wave magnets
Jan Priessnitz, Anna Birk Hellenes, Riccardo Comin +1
Couplings between ferroelectric and magnetic orders offer promising routes toward low-dissipation electronics. However, such couplings are notably rare, largely due to the poor com…
Persistent altermagnetism
Warlley H. Campos, F. C. Fobasso Mbognou, Anna Birk Hellenes +4
Persistent spin textures with collinear spin polarization are promising platforms for spintronics applications. However, their typically relativistic spin-orbit origin leads to wea…
Microscopic origin of -wave magnetism
Johannes Mitscherling, Jan Priessnitz, Clara K. Geschner +1
-, -, or -wave antialtermagnets yield large non-relativistic spin splitting with out-of-plane spin polarization in momentum space perpendicular to the coplanar non-colline…
Topological textures and emergent altermagnetic signatures in ultrathin BiFeO3
George Fratian, Maya Ramesh, Xinyan Li +23
Magnetoelectric multiferroics, materials with intrinsically coupled electric polarization and magnetic order, promise ultralow-power switching, nonvolatile memory, and energy-effic…
Quantization of spin circular photogalvanic effect in altermagnetic Weyl semimetals
Hiroki Yoshida, Jan Priessnitz, Libor Å mejkal +1
We theoretically predict a spin-current analog of the quantized circular photogalvanic effect in Weyl semimetals. This phenomenon is forbidden in antiferromagnets by symmetry but u…
Orbital magnetization from parallel transport of Bloch states
Johannes Mitscherling, Jan Priessnitz, Libor Å mejkal
Quantum geometric formulations of linear and nonlinear responses can be constructed from a single building block in the form of a gauge-invariant interband transition operator. Her…
