Strong antiferromagnetic proximity coupling in a heterostructured superconductor SrVOFeAs
Jong Mok Ok, Chang Il Kwon, O. E. Ayala Valenzuela +10
We report observation of strong magnetic proximity coupling in a heterostructured superconductor SrVOFeAs, determined by the upper critical fields measurements…
Proximity-induced hidden order transition in a correlated heterostructure SrVOFeAs
Sunghun Kim, Jong Mok Ok, Hanbit Oh +10
Symmetry is one of the most significant concepts in physics, and its importance has been largely manifested in phase transitions by its spontaneous breaking. In strongly correlated…
Direct observation of excitonic instability in Ta2NiSe5
Kwangrae Kim, Hoon Kim, Jonghwan Kim +3
Coulomb attraction between electrons and holes in a narrow-gap semiconductor or a semimetal is predicted to lead to an elusive phase of matter dubbed 'excitonic insulator'. However…
Observation of the in-plane magnetic field-induced phase transitions in FeSe
Jong Mok Ok, Chang Il Kwon, Yoshimitsu Kohama +11
We investigate the thermodynamic properties of FeSe under the in-plane magnetic fields using torque magnetometry, specific heat, magnetocaloric measurements. Below the upper critic…
Lifted electron pocket and reversed orbital occupancy imbalance in FeSe
Soonsang Huh, Jeongjin Seo, Beomseo Kim +13
The FeSe nematic phase has been the focus of recent research on iron based superconductors (IBSs) due to its unique properties. A number of electronic structure studies were perfor…
