Softening of breathing elastic mode and trigonal elastic mode in disordered pyrochlore magnet NaCaCoF
T. Watanabe, H. Kato, Y. Hara +2
Cobalt pyrochlore fluoride NaCaCoF is a disordered frustrated magnet composed of Co ions with an effective spin- magnetic moment and exhibits spin freez…
Double pair breaking peak in Raman scattering spectra of triple layer cuprate Bi2223
Giulio Vincini, K. Tanaka, T. Adachi +6
We report the Raman scattering measurements on the triple layer Bi2Sr2Ca2Cu3O10 (Bi2223) crystals of four different doping levels from slightly overdoped to strongly underdoped reg…
Orbital- and spin-driven lattice instabilities in quasi-one-dimensional CaVO
T. Watanabe, S. Kobayashi, Y. Hara +5
Calcium vanadate CaVO has a crystal structure of quasi-one-dimensional zigzag chains composed of orbital-active V ions and undergoes successive structural and antife…
Electronic structure of Mott-insulator CaCu3Ti4O12: Photoemission and inverse photoemission study
H. J. Im, M. Iwataki, S. Yamazaki +10
We have performed the photoemission and inverse photoemission experiments to elucidate the origin of Mott insulating states in A-site ordered perovskite CaCuTiO (CCT…
Evolution of superconductivity in LaO1-xFxBiS2 prepared by high pressure technique
K. Deguchi, Y. Mizuguchi, S. Demura +10
Novel BiS2-based superconductors LaO1-xFxBiS2 prepared by the high pressure synthesis technique were systematically studied. It was found that the high pressure annealing strongly…
Fermiological Interpretation of Superconductivity/Non-superconductivity of FeTe_{1-x}Se_{x} Thin Crystal Determined by Quantum Oscillation Measurement
H. Okazaki, T. Watanabe, T. Yamaguchi +8
We have successfully observed quantum oscillation (QO) for FeTe_{1-x}Se_{x}. QO measurements were performed using non-superconducting and superconducting thin crystals of FeTe_{0.6…
