Coexistence of insulator-like paramagnon and metallic spin-orbit exciton modes in SrIrO
Eugenio Paris, Wenliang Zhang, Yi Tseng +13
We probe the spectrum of elementary excitations in SrIrO by using heterostructured [(SrIrO)/(SrTiO)] samples to approach the bulk limit. Our resonant inelastic…
Dynamic Jahn-Teller effect in the strong spin-orbit coupling regime
Ivica Zivkovic, Jian-Rui Soh, Oleg Malanyuk +15
Exotic quantum phases, arising from a complex interplay of charge, spin, lattice and orbital degrees of freedom, are of immense interest to a wide research community. A well-known…
Persistent quantum vibronic dynamics in a double perovskite oxide
Naoya Iwahara, Jian-Rui Soh, Daigorou Hirai +10
Quantum entanglement between the spin, orbital, and lattice degrees of freedom in condensed matter systems can emerge due to an interplay between spin-orbit and vibronic interactio…
Spin-orbital excitations encoding the magnetic phase transition in the van der Waals antiferromagnet FePS
Yuan Wei, Yi Tseng, Hebatalla Elnaggar +13
In the rich phases of van der Waals (vdW) materials featuring intertwined electronic order and collective phenomena, characterizing elementary dynamics that entail the low-energy H…
Unraveling the Mn -edge RIXS spectrum of lightly manganese doped SrRuO
Wei-Yang Chen, Shih-Wen Huang, Yi Tseng +10
Resonant inelastic x-ray scattering (RIXS) experiment was performed at the Mn edge. A 10 Mn-doped SrRuO compound, where the Mn ions are in the 3…
Emergence of interfacial magnetism in strongly-correlated nickelate-titanate superlattices
Teguh Citra Asmara, Robert J. Green, Andreas Suter +21
Strongly-correlated transition-metal oxides are widely known for their various exotic phenomena. This is exemplified by rare-earth nickelates such as LaNiO, which possess int…
