Infrared optical absorption spectra of CuO single crystals: Fermion-spinon band and dimensional crossover of the antiferromagnetic order
SeongHoon Jung, Jooyeon Kim, E. J. Choi +3
We have obtained mid-infrared optical absorption spectra of the S=1/2 quasi one-dimensional CuO using polarized transmission measurement and interpreted the spectra in terms of pho…
Multiple-source optical spectral weight transfer in ferromagnetic EuB6
Jungho Kim, B. K. Cho, Young-June Kim +1
We present the first wide range (2 meV5.5 eV) optical conductivity of EuB from reflectivity and ellipsometry measurements. Upon the ferromagnetic transition at T=15.5…
Infrared Hall conductivity of NaCoO
E. J. Choi, S. H. Jung, J. H. Noh +5
We report infrared Hall conductivity of NaCoO thin films determined from Faraday rotation angle measurements. exhibits two types of hole…
Infrared study of giant dielectric constant in Li and Ti doped NiO
Jung-Ho Kim, Youngwoo Lee, A Souchkov +5
We have measured optical reflectivity of Li and Ti doped NiO (LTNO) in the infrared range at various temperatures. A Drude-like absorption is found at low energy, 100 cm$^{-1}…
Optical spectroscopy study on the electronic structure of
Jungho Kim, S. -J. Oh, Youngwoo Lee +4
The optical conductivity of EuCaB has been obtained from reflectivity and ellipsometry measurements for series of compositions, . The…
Photoemission and x-ray absorption study of MgC_(1-x)Ni_3
J. H. Kim, J. S. Ahn, Jinsoo Kim +4
We investigated electronic structure of MgC_(1-x)Ni_3 with photoemission and x-ray absorption spectroscopy. Both results show that overall band structure is in reasonable agreement…
