Rational Control of Magnonic and Electronic Band Splittings
Subhadeep Bandyopadhyay, Anoop Raj, Philippe Ghosez +2
We provide a theoretical demonstration of controllable non-relativistic spin splitting in both electronic and magnonic bands via targeted structural distortions tied to specific ph…
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…
Electric toroidal dipole order and hidden spin polarization in ferroaxial materials
Sayantika Bhowal, Nicola A. Spaldin
We investigate the role of electric toroidal dipoles in the prototypical ferroaxial materials NiTiO and KZr(PO), which undergo ferroaxial structural phase transitio…
Non-relativistic ferromagnetotriakontadipolar order and spin splitting in hematite
X. H. Verbeek, D. Voderholzer, S. Schären +3
We show that hematite, -FeO, below its Morin transition, has a ferroic ordering of rank-5 magnetic triakontadipoles on the Fe ions. In the absence of spin-orbit coupling…
