Linear and nonlinear optical probe of the ferroelectric-like phase transition in a polar metal, LiOsO3
Haricharan Padmanabhan, Yoonsang Park, Danilo Puggioni +7
LiOsO3 is one of the first materials identified in a recent literature as a 'polar metal', a class of materials that are simultaneously noncentrosymmetric and metallic. In this wor…
Magnetite: Raman study of the high-pressure and low-temperature effects
L. V. Gasparov, D. Arenas, K. -Y. Choi +6
We report the results of a low-temperature (300K-15K) high-pressure (up to 22GPa) Raman study of the Verwey transition in magnetite (Fe3O4). We use additional Raman modes observed…
Phonon anomaly at the charge ordering transition in 1T-TaS2
L. V. Gasparov, K. G. Brown, A. C. Wint +5
The infrared reflectance of the transition metal chalcogenide 1T-TaS2 has been measured at temperatures from 30K to 360K over 30-45,000cm^-1 (4meV-5.5eV). The optical conductivity…
Infrared and Raman studies of the Verwey transition in magnetite
L. V. Gasparov, D. B. Tanner, D. B. Romero +4
We present infrared and Raman measurements of magnetite (Fe_3O_4). This material is known to undergo a metal-insulator and a structural transition (Verwey transition) at T_V=120K.…
Electronic Raman scattering in the single-CuO2 layered superconductor Tl2Ba2CuO6+x
L. V. Gasparov, P. Lemmens, M. Brinkmann +2
Electronic Raman scattering in Tl-2201 has been investigated in order to test whether the scattering cross-section in high temperature superconductors depends on the number of CuO2…
