Charge states and magnetic ordering in LaMnO3/SrTiO3 superlattices
Woo Seok Choi, D. W. Jeong, S. S. A. Seo +5
We investigated the magnetic and optical properties of [(LaMnO3)n/(SrTiO3)8]20 (n = 1, 2, and 8) superlattices grown by pulsed laser deposition. We found a weak ferromagnetic and s…
Electronic structure and anomalous band-edge absorption feature in multiferroic MnWO4: An optical spectroscopic study
Woo Seok Choi, K. Taniguchi, S. J. Moon +6
We investigated the electronic structure and lattice dynamics of multiferroic MnWO4 by optical spectroscopy. With variation of polarization, temperature, and magnetic field, we obt…
Optical spectroscopic investigation on the temperature-dependent electronic structure evolution of the Jeff,1/2 Mott insulator Sr2IrO4
S. J. Moon, Hosub Jin, W. S. Choi +6
We investigated the temperature-dependent evolution of the electronic structure of the Jeff,1/2 Mott insulator Sr2IrO4 using optical spectroscopy. The optical conductivity spectra…
Optical spectroscopic investigation on the coupling of electronic and magnetic structure in multiferroic hexagonal RMnO3 (R = Gd, Tb, Dy, and Ho) thin films
Woo Seok Choi, Soon Jae Moon, Sung Seok A. Seo +5
We investigated the effects of temperature and magnetic field on the electronic structure of hexagonal RMnO3 (R = Gd, Tb, Dy, and Ho) thin films using optical spectroscopy. As the…
Signatures of Electronic Correlations in Optical Properties of LaFeAsOF
A. V. Boris, N. N. Kovaleva, S. S. A. Seo +5
Spectroscopic ellipsometry is used to determine the dielectric function of the superconducting LaFeAsOF ( = 27 K) and undoped LaFeAsO polycrystalline samples i…
Ferroelectricity in artificial bicolor oxide superlattices
Sung Seok A. Seo, Jun Hee Lee, Ho Nyung Lee +7
We report on the growth and properties of high quality bicolor oxide superlattices, composed of two perovskites out of BaTiO3, CaTiO3, and SrTiO3. The artificially grown superlatti…
