Tuning orbital-selective phase transitions in a two-dimensional Hund's correlated system
Eun Kyo Ko, Sungsoo Hahn, Changhee Sohn +12
Hund's rule coupling () has attracted much attention recently for its role in the description of the novel quantum phases of multi orbital materials. Depending on the o…
Heteroepitaxial control of Fermi liquid, Hund metal, and Mott insulator phases in the single-atomic-layer limit
Jeong Rae Kim, Byungmin Sohn, Hyeong Jun Lee +16
Interfaces between dissimilar correlated oxides can offer devices with versatile functionalities. In that respect, manipulating and measuring novel physical properties of oxide het…
Flexoelectric control of a ferromagnetic metal
Wei Peng, Se Young Park, Chang Jae Roh +16
Electric fields have played a key role in discovering and controlling exotic electronic states of condensed matter. However, electric fields usually do not work in metals as free c…
Observation of spin-dependent dual ferromagnetism in perovskite ruthenates
Sungsoo Hahn, Byungmin Sohn, Minjae Kim +10
We performed in-situ angle-resolved photoemission spectroscopy (ARPES) and spin-resolved ARPES (SARPES) experiments to investigate the relationship between electronic band structur…
Observation of metallic electronic structure in a single-atomic-layer oxide
Byungmin Sohn, Jeong Rae Kim, Choong H. Kim +11
Correlated electrons in transition metal oxides (TMOs) exhibit a variety of emergent phases. When TMOs are confined to a single-atomic-layer thickness, experiments so far have show…
Capping and gate control of anomalous Hall effect and hump structure in ultra-thin SrRuO films
Donghan Kim, Byungmin Sohn, Minsoo Kim +5
Ferromagnetism and exotic topological structures in SrRuO (SRO) induce sign-changing anomalous Hall effect (AHE). Recently, hump structures have been reported in the Hall resis…
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…
