Symmetry-isolated magnetoelectric electro-optic effects in noncentrosymmetric metals
C. O. Ascencio, D. J. P. de Sousa, Seungjun Lee +1
We classify the symmetry-constrained forms of the Berry curvature dipole , gyrotropic magnetic tensor , and magnetoelectric electro-optic (EO) tensor $\math…
Epitaxial Strain Activates Altermagnetic Spin-Splitting Torques in RuO2(100)
Qi Jia, Seung Gyo Jeong, Seungjun Lee +10
The altermagnetic nature of rutile RuO2 remains under active debate: bulk measurements indicate a nearly nonmagnetic ground state, whereas thin-film studies have reported symmetry-…
Strain-Driven Altermagnetic Spin Splitting Effect in RuO
Seungjun Lee, Seung Gyo Jeong, Jian-Ping Wang +2
The non-relativistic spin-momentum locking in altermagnets gives rise to a time-reversal-odd spin Hall effect, known as the altermagnetic spin-splitting effect (ASSE). Although ASS…
Strain Engineering of Altermagnetic Symmetry in Epitaxial RuO Films
Johnathas D. S. Forte, Seung Gyo Jeong, Anand Santhosh +3
The magnetic ground state of RuO has been under intense debate. Using first-principles calculations, we show that compressive strain along [001] direction stabilizes an alterma…
Observation of mirror-odd and mirror-even spin texture in ultrathin epitaxially strained RuO2 films
Yichen Zhang, Seung Gyo Jeong, Luca Buiarelli +24
Recently, rutile ruthenium dioxide (RuO) has attracted renewed interest due to expectations of prominent altermagnetic spin splitting. However, accumulating experimental eviden…
Emergent superconductivity and non-reciprocal transport in a van der Waals Dirac semimetal/antiferromagnet heterostructure
Saurav Islam, Max Stanley, Anthony Richardella +6
We investigate emergent superconductivity and non-reciprocal transport (magnetochiral anisotropy, superconducting diode effect) at the heterointerface of two non-superconducting va…
