Electric control of two-dimensional Van Hove singularity in oxide ultra-thin films
Donghan Kim, Younsik Kim, Byungmin Sohn +4
Divergent density of states (DOS) can induce extraordinary phenomena such as significant enhancement of superconductivity and unexpected phase transitions. Moreover, van Hove singu…
Electronic band structure of (111) thin filman angle-resolved photoemission spectroscopy study
Hanyoung Ryu, Yukiaki Ishida, Bongju Kim +16
We studied the electronic band structure of pulsed laser deposition (PLD) grown (111)-oriented SrRuO (SRO) thin films using \textit{in situ} angle-resolved photoemission spectr…
Sign-tunable anomalous Hall effect induced by two-dimensional symmetry-protected nodal structures in ferromagnetic perovskite oxide thin films
Byungmin Sohn, Eunwoo Lee, Se Young Park +16
Magnetism and spin-orbit coupling (SOC) are two quintessential ingredients underlying novel topological transport phenomena in itinerant ferromagnets. When spin-polarized bands sup…
Hump-like structure in Hall signal from SrRuO ultra-thin films without inhomogeneous anomalous Hall effect
Byungmin Sohn, Bongju Kim, Jun Woo Choi +3
A controversy arose over the interpretation of the recently observed hump features in Hall resistivity from ultra-thin SrRuO (SRO) film; it was initially interpreted t…
Orbital-selective confinement effect of Ru orbitals in SrRuO ultrathin film
Soonmin Kang, Yi Tseng, Beom Hyun Kim +11
The electronic structure of SrRuO thin film with thickness from 50 to 1 unit cell (u.c.) is investigated via the resonant inelastic x-ray scattering (RIXS) technique at the O K…
Stable hump-like Hall effect and non-coplanar spin textures in SrRuO ultrathin film
Byungmin Sohn, Bongju Kim, Se Young Park +11
We observed a hump-like feature in Hall effects of SrRuO ultrathin films, and systematically investigated it with controlling thicknesses, temperatures and magnetic fields. The…
