Tunable electronic and magnetic phases in layered ruthenates: SrRuO3-SrTiO3 heterostructure upon strain
Minjae Kim, Chang-Jong Kang, Jae-Ho Han +2
Layered ruthenates are a unique class of systems which manifests a variety of electronic and magnetic features emerged from competing energy scales. At the heart of such features l…
Ferroelectricity driven by magnetism in quasi-one-dimensional Ba9Fe3Se15
Jun Zhang, Xiancheng Wang, Yiqing Hao +13
The spin-induced ferroelectricity in quasi-1D spin chain system is little known, which could be fundamentally different from those in three-dimensional (3D) system. Here, we report…
Coexisting Kondo hybridization and itinerant f-electron ferromagnetism in UGe2
Ioannis Giannakis, Divyanshi Sar, Joel Friedman +6
Kondo hybridization in partially filled f-electron systems conveys significant amount of electronic states sharply near the Fermi energy leading to various instabilities from super…
Phase stability and large in-plane resistivity in the 112-type iron-based superconductor CaLaFeAs
Chang-Jong Kang, Turan Birol, Gabriel Kotliar
The recently discovered high-T superconductor CaLaFeAs is a unique compound not only because of its low symmetry crystal structure, but also because of its…
Topological properties and the dynamical crossover from mixed-valence to Kondo-lattice behavior in golden phase of SmS
Chang-Jong Kang, Hong Chul Choi, Kyoo Kim +1
We have investigated temperature-dependent behaviors of electronic structure and resistivity in a mixed-valent golden phase of SmS, based on the dynamical mean-field theory band st…
Termination-dependent Surface In-gap States in a Mixed-valent Topological Insulator: SmB
Junwon Kim, Kyoo Kim, Chang-Jong Kang +5
We have investigated the surface states of a potential mixed-valent topological insulator SmB based on the first principles density functional theory slab band structure analys…
