Correlation between $T_{c}$ and the Pseudogap Observed in the Optical Spectra of High $T_{c}$ Superconducting Cuprates

Setsuko Tajima, Yuhta Itoh, Katsuya Mizutamari +6

We studied the temperature dependences of the optical spectra for optimally and underdoped Bi $_{2}$ Sr $_{2}$ Ca $_{2}$ Cu $_{3}$ O $_{10 + z}$ single crystals. Similarly to the other cuprates' case…

High- $T_{c}$ Iron-phosphide Superconductivity Enhanced by Reemergent Antiferromagnetic Spin Fluctuations in (Sr $_{4}$ Sc $_{2}$ O $_{6}$ )Fe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$ probed by NMR

F. Sakano, K. Nakamura, T. Kouchi +13

We report a systematic NMR study on [Sr $_{4}$ Sc $_{2}$ O $_{6}$ ]Fe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$ , for which the local lattice parameters of the iron-pnictogen (Fe $P n$ ) layer are similar to those…

Multiple Antiferromagnetic Spin Fluctuations and Novel Evolution of Tc in Iron-based superconductors LaFe(As1-xPx)(O1-yFy) revealed by 31P-NMR Studies

T. Shiota, H. Mukuda, M. Uekubo +8

We report on 31P-NMR studies of LaFe(As_{1-x}P_x)(O_{1-y}F_{y}) over wide compositions for 0<x<1 and 0<y<0.14, which provide clear evidence that antiferromagnetic spin fluctuations…

Optical Study of BaFe $_{2}$ As $_{2}$ 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 $^{- 1}$ were performed on BaFe $_{2}$ As $_{2}$ single crystals under pressure up to $\sim$ 5 GPa. The co…

Effect of magnetism on lattice dynamics in SrFe $_{2}$ As $_{2}$ as seen via high resolution inelastic x-ray scattering

N. Murai, T. Fukuda, T. Kobayashi +9

Phonon spectra of detwinned {SrFe $_{2}$ As $_{2}$ } crystals, as measured by inelastic x-ray scattering, show clear anisotropy accompanying the magneto-structural transition at 200 K. We…
