Multipoles as quantitative order parameters for altermagnetic spin splitting
Francesco Martinelli, Anouk Droux, Claude Ederer
We establish a quantitative relation between the altermagnetic spin-splitting and different higher order multipoles of the charge and magnetization density around the magnetic atom…
Oxygen vacancies in vanadium dioxide: A DFT study
Oskar Leibnitz, Peter Mlkvik, Nicola A. Spaldin +1
We present a density-functional theory study of the effects of oxygen vacancies on the structural and electronic properties of vanadium dioxide (VO). Our motivation is the repo…
Effects of strain on the stability of the metallic rutile and insulating M1 phases of vanadium dioxide
Peter Mlkvik, Lena Geistlich, Nicola A. Spaldin +1
We present a systematic density-functional theory study of the effects of strain on the structural and electronic properties in vanadium dioxide (VO), with particular emphasis…
(Anti-)Altermagnetism from Orbital Ordering in the Ruddlesden-Popper Chromates SrCrO
Quintin N. Meier, Alberto Carta, Claude Ederer +1
Altermagnets are collinear antiferromagnets with spin-split electronic states. We introduce Ruddlesden-Popper chromates SrCrO (including SrCrO) as candidat…
