Direct observation of the lattice dynamics of transition metals using ultrafast electron diffraction
A. Nakamura, T. Shimojima, M. Nakano +2
We report the lattice dynamics of transition metal thin films by using the ultrafast electron diffraction. We observe a suppression of the diffraction intensity in a few picosecond…
Evidence for exclusion of the possibility of -wave superconducting-gap symmetry in Ba-doped KFeAs
Y. Ota, K. Okazaki, Y. Kotani +12
We have investigated the superconducting(SC)-gap anisotropy for several Ba-doped KFeAs samples using laser-based angle-resolved photoemission spectroscopy. We show that the…
Importance of both spin and orbital fluctuations in BaFe2(As1-xPx)2 : Evidence from superconducting gap anisotropy
T. Yoshida, S. Ideta, T. Shimojima +32
In the iron pnictide superconductors, two distinct unconventional mechanisms of superconductivity have been put forth: One is mediated by spin fluctuations leading to the s+- state…
Anomalous two peak structure in the Angle-resolved Photoemission Spectra of Ba1-xKxFe2As2
T. Shimojima, W. Malaeb, K. Ohgushi +13
The electronic structure near the Fermi level (EF) of Ba1-xKxFe2As2 (BaK122 ; x = 0.2 - 0.7) is studied using laser ultrahigh-resolution angle-resolved photoemission spectroscopy(A…
Angle-resolved photoemission study of cobalt oxide superconductor NaxCoO2.yH2O : Observation of the Fermi surface
T. Shimojima, K. Ishizaka, S. Tsuda +7
Cobalt oxide superconductor NaxCoO2.yH2O is studied by angle-resolved photoemission spectroscopy (ARPES). We report the Fermi surface (FS) topology and electronic structure near th…
