Odd-parity surface magnetism in a Kondo insulator
Maxim Dzero, Brian M. Andersen
We formulate a theory of spin-polarized tunneling between a nanowire tip of a topological Kondo insulator SmB and the bi-collinear antiferromagnet FeTe in which the tun…
Multi-orbital physics in inverse Lieb lattice altermagnets
Mercè Roig, Jannik Gondolf, Andreas Kreisel +2
The inverse Lieb lattice has recently emerged as a promising platform for altermagnetism, with several materials with this structure proposed as -wave altermagnetic candidates.…
Robust spin splitting and fermiology in the layered altermagnet CoNb4Se8
Alessandro De Vita, Chiara Bigi, Davide Romanin +44
Altermagnetism defies conventional classifications of collinear magnetic phases, combining compensated magnetization with momentum-dependent, nonrelativistic spin splitting. While…
Local signatures of altermagnetism
Jannik Gondolf, Andreas Kreisel, Mercè Roig +3
Altermagnets constitute a class of collinear compensated Néel ordered magnets that break time-reversal symmetry and feature spin-split band structures. Based on versatile microscop…
Odd-parity Magnetism Driven by Antiferromagnetic Exchange
Yue Yu, Magnus B. Lyngby, Tatsuya Shishidou +5
Realizing odd-parity, time-reversal-preserving, non-relativistic spin splitting is a central goal for spintronics applications. We propose a group-theory-based microscopic framewor…
Quasi-symmetry Constrained Spin Ferromagnetism in Altermagnets
Mercè Roig, Yue Yu, Rune C. Ekman +3
Altermagnets break time-reversal symmetry and their spin-orbit coupling (SOC) allow for an anomalous Hall effect (AHE) that depends on the direction of the Néel ordering vector. Th…
Minimal Models for Altermagnetism
Mercè Roig, Andreas Kreisel, Yue Yu +2
Altermagnets feature vanishing net magnetization, like antiferromagnets, but exhibit time-reversal symmetry breaking and momentum-dependent spin-split band structures. Motivated by…
