Revisiting the symmetry and optical phonons of altermagnetic -MnTe
Ece Uykur, Marcos V. Gonçalves-Faria, Sahana Rößler +5
Using infrared (IR) and Raman spectroscopies combined with high-resolution x-ray diffraction, we address several controversial aspects of altermagnetic -MnTe. We show that mecha…
Optical spectroscopy study on pressure-induced phase transitions in the three-dimensional Dirac semimetal CdAs
E. Uykur, R. Sankar, D. Schmitz +1
We report a room-temperature optical reflectivity study performed on [112]-oriented CdAs single crystals over a broad energy range under external pressure up to 10 GPa. The…
Optical Study of BaFeAs under pressure: Coexistence of spin-density-wave gap and superconductivity
E. Uykur, T. Kobayashi, W. Hirata +3
Temperature-dependent reflectivity measurements in the frequency range 85 - 7000 cm were performed on BaFeAs single crystals under pressure up to 5 GPa. The co…
Persistence of superconducting condensate far above the critical temperature in YBa(Cu,Zn)O revealed by -axis optical conductivity measurements for several Zn concentrations and carrier doping levels
Ece Uykur, Kiyohisa Tanaka, Takahiko Masui +2
The superconductivity precursor phenomena in high temperature cuprate superconductors was studied by direct measurements of superconducting condensate with the use of the -axis…
Coexistence of the Pseudogap and the Superconducting Gap Revealed by the \textit{c}-axis Optical Study of YBa(CuZn)O
Ece Uykur, Kiyohisa Tanaka, Takahiko Masui +2
To address the issue of the pseudogap in the superconducting state of the high temperature superconducting cuprates, we studied the temperature dependent redistribution of the spec…
In-plane optical spectra of YCaBaCuO: Overdoping and disorder effect on residual conductivity
E. Uykur, K. Tanaka, T. Masui +2
We measured the temperature dependence of the in-plane polarized reflectivity spectra of twin-free YCaBaCuO single crystals with different Ca-conc…
