Photoinduced phase switching at a Mott insulator-to-metal transition
K. S. Rabinovich, A. N. Yaresko, R. D. Dawson +5
Achieving fundamental understanding of insulator-to-metal transitions (IMTs) in strongly correlated systems and their persistent and reversible control via nonequilibrium drive are…
Infrared phonon spectra of quasi-one-dimensional TaNiSe and TaNiS
T. I. Larkin, R. D. Dawson, M. Höppner +6
Using a combination of infrared ellipsometry, time-domain terahertz spectroscopy, and far-infrared reflectometry we have obtained the -plane complex dielectric function of mono…
Optical anisotropy of the Jeff = 1/2 Mott insulator Sr2IrO4
D. Pröpper, A. N. Yaresko, M. Höppner +7
We report the complex dielectric function along and perpendicular to the IrO2 planes in the layered perovskite Sr2IrO4 determined by spectroscopic ellipsometry in the spectral rang…
Crystal growth and intrinsic magnetic behavior of SrIrO
N. H. Sung, H. Gretarsson, D. Proepper +5
We report on the growth of stoichiometric SrIrO single crystals, which allow us to unveil their intrinsic magnetic properties. The effect of different growth conditions has…
Orbital control of noncollinear magnetic order in nickelate heterostructures
A. Frano, E. Schierle, M. W. Haverkort +13
We have used resonant x-ray diffraction to develop a detailed description of antiferromagnetic ordering in epitaxial superlattices based on two-unit-cell thick layers of the strong…
Dimensionality Control of Electronic Phase Transitions in Nickel-Oxide Superlattices
A. V. Boris, Y. Matiks, E. Benckiser +15
The competition between collective quantum phases in materials with strongly correlated electrons depends sensitively on the dimensionality of the electron system, which is difficu…
Ferromagnetism and Lattice Distortions in the Perovskite YTiO
W. Knafo, C. Meingast, H. v. Löhneysen +7
The thermodynamic properties of the ferromagnetic perovskite YTiO are investigated by thermal expansion, magnetostriction, specific heat, and magnetization measurements. The lo…
Spin-controlled Mott-Hubbard bands in LaMnO_3 probed by optical ellipsometry
N. N. Kovaleva, A. V. Boris, C. Bernhard +5
Spectral ellipsometry has been used to determine the dielectric function of an untwinned crystal of LaMnO_3 in the spectral range 0.5-5.6 eV at temperatures 50 K < T < 300 K. A pro…
Magnetism, Charge Order and Giant Magnetoresistance in SrFeO Single Crystals
A. Lebon, P. Adler, C. Bernhard +6
The electronic and magnetic properties of SrFeO single crystals with controlled oxygen content () have been studied systematically by susceptibility, tra…
Phonon anomalies and electron-phonon interaction in RuSr_2GdCu_2O_8 ferromagnetic superconductor: Evidence from infrared conductivity
A. V. Boris, P. Mandal, C. Bernhard +4
Critical behavior of the infrared reflectivity of RuSr_2GdCu_2O_8 ceramics is observed near the superconducting T_{SC} = 45 K and magnetic T_M = 133 K transition temperatures. The…
