Experimental confirmation of the magnetic ordering transition induced by an electronic structure change in the metallic triangular antiferromagnet CoTaS
Han-Jin Noh, En-Jin Cho, Byeong-Gyu Park +6
We report ARPES studies combined with DFT+DMFT calculations to confirm that the magnetic ordering vector transition from \textbf{Q}=(1/2,0,0) to \textbf{Q}=(1/3,0,0) in the metalli…
Tetrahedral triple-Q magnetic ordering and large spontaneous Hall conductivity in the metallic triangular antiferromagnet Co1/3TaS2
Pyeongjae Park, Woonghee Cho, Chaebin Kim +14
The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is t…
Semimetallic Nature and Magnetic Polarons in EuB6 Studied by Angle-Resolved Photoemission Spectroscopy
Chul-Hee Min, Boyoun Kang, Beong Ki Cho +3
Temperature-dependent angle-resolved photoemission spectroscopy (ARPES) was carried out on single-crystalline EuB6 samples. By measuring ARPES spectra in an extended Brillouin zone…
Electronic Structure Change of NiSSe in the Metal-Insulator Transition Probed by X-ray Absorption Spectroscopy
Jinwon Jeong, Kyung Ja Park, En-Jin Cho +3
The electronic structure change of NiSSe as a function of Se concentration has been studied by Ni -edge X-ray absorption spectroscopy (XAS). The XAS spectra show…
Experimental Realization of Type-II Dirac Fermions in PdTe Superconductor
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +3
A Dirac fermion in a topological Dirac semimetal is a quadruple-degenerate quasi-particle state with a relativistic linear dispersion. Breaking either time-reversal or inversion sy…
Controlling the 2DEG states evolution at a metal/BiSe interface
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +5
We have demonstrated that the evolution of the two-dimensional electron gas (2DEG) system at an interface of metal and the model topological insulator (TI) BiSe can be cont…
