Strain-driven spin-flop transition and collapse of the giant magnon gap in the bilayer iridate SrIrO
Choong H. Kim
The bilayer iridate SrIrO is a -axis collinear antiferromagnet, held there by a giant interlayer pseudodipolar anisotropy, whereas single-layer SrIrO cants i…
Classification of magnetic order from electronic structure by using machine learning
Yerin Jang, Choong H. Kim, Ara Go
Identifying the magnetic state of materials is of great interest in a wide range of applications, but direct identification is not always straightforward due to limitations in neut…
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…
Ferroelectricity-driven phonon Berry curvature and non-linear phonon Hall transports
Jino Im, Choong H. Kim, Hosub Jin
Berry curvature (BC) governs topological phases of matter and generates anomalous transport. When a magnetic field is applied, phonons can acquire BC indirectly through spin-lattic…
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…
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…
