Optical transitions of a single nodal ring in SrAs: radially and axially resolved characterization
Jiwon Jeon, Jiho Jang, Hoil Kim +7
SrAs is a unique nodal-line semimetal that contains only a single nodal ring in the Brillouin zone, uninterrupted by any trivial bands near the Fermi energy. We performed axis-…
Observation of Kondo condensation in a degenerately doped silicon metal
H. Im, D. U. Lee, Y. Jo +10
When a magnetic moment is embedded in a metal, it captures itinerant electrons to form the Kondo cloud1,2, which can spread out over a few micrometres3,4. For a metal with dense ma…
Magneto-Elastic Coupling to Coherent Acoustic Phonon Modes in Ferrimagnetic Insulator GdTiO
D. J. Lovinger, E. Zoghlin, P. Kissin +8
In this work we investigate single crystal GdTiO, a promising candidate material for Floquet engineering and magnetic control, using ultrafast optical pump-probe reflectivity…
SrIrOF: Topochemical conversion of a relativistic Mott state into a spin-orbit driven band insulator
Christi Peterson, Michael W. Swift, Zach Porter +9
The topochemical transformation of single crystals of SrIrO into SrIrOF is reported via fluorine insertion. Characterization of the newly formed SrI…
Charge-spin correlation in van der Waals antiferromagenet NiPS3
So Yeun Kim, Tae Yun Kim, Luke J. Sandilands +13
Strong charge-spin coupling is found in a layered transition-metal trichalcogenide NiPS3, a van derWaals antiferromagnet, from our study of the electronic structure using several e…
Dimensionality Control of d-orbital Occupation in Oxide Superlattices
Da Woon Jeong, Woo Seok Choi, Satoshi Okamoto +6
Manipulating the orbital state in a strongly correlated electron system is of fundamental and technological importance for exploring and developing novel electronic phases. Here, w…
