Strain-induced Dynamic Spin-Phonon Coupling in Epitaxial RuO2 Films
In Hyeok Choi, Seung Gyo Jeong2, Seung Gyo Jeong +7
Magnetic order parameters in altermagnets can couple to quantized lattice vibration via both piezomagnetic and magnetoelastic effects, leading to the renormalization of phonon disp…
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…
Strain-Stabilized Interfacial Polarization Tunes Work Function Over 1 eV in RuO2/TiO2 Heterostructures
Seung Gyo Jeong, Bonnie Y. X. Lin, Mengru Jin +14
Interfacial polarization-charge accumulation at the heterointerface-is a well-established tool in semiconductors, but its influence in metals remains unexplored. Here, we demonstra…
Anisotropic Strain Relaxation-Induced Directional Ultrafast Carrier Dynamics in RuO2 Films
S. G. Jeong, I. H. Choi, S. Lee +9
Ultrafast light-matter interactions inspire potential functionalities in picosecond optoelectronic applications. However, achieving directional carrier dynamics in metals remains c…
Metallicity and Anomalous Hall Effect in Epitaxially-Strained, Atomically-thin RuO2 Films
Seung Gyo Jeong, Seungjun Lee, Bonnie Lin +14
The anomalous Hall effect (AHE), a hallmark of time-reversal symmetry breaking, has been reported in rutile RuO2, a debated metallic altermagnetic candidate. Previously, AHE in RuO…
