Electric field driven octahedral rotation in perovskite
Wonshik Kyung, Choong H. Kim, Yeong Kwan Kim +9
Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most imp…
Spin-orbit coupling effects on spin-phonon coupling in Cd2Os2O7
Taehun Kim, Choong H. Kim, Jaehong Jeong +8
Spin-orbit coupling (SOC) is essential in understanding the properties of 5d transition metal compounds, whose SOC value is large and almost comparable to other key parameters. Ove…
Interplay between spin-orbit coupling and van Hove singularity in the Hund's metallicity of SrRuO
Hyeong Jun Lee, Choong H. Kim, Ara Go
We investigate the dynamical properties of SrRuO at zero and very low temperature using density functional theory plus dynamical mean-field theory with an exact diagonaliza…
