Direct Search for a Ferromagnetic Phase in a Heavily Overdoped Nonsuperconducting Copper Oxide
J. E. Sonier, C. V. Kaiser, V. Pacradouni +5
The doping of charge carriers into the CuO2 planes of copper oxide Mott insulators causes a gradual destruction of antiferromagnetism and the emergence of high-temperature supercon…
Superconductivity of FeSe0.5Te0.5 Thin Films Grown by Pulsed Laser Deposition
Yoshinori Imai, Ryo Tanaka, Takanori Akiike +3
FeSe0.5Te0.5 thin films with PbO-type structure are successfully grown on MgO(100) and LaSrAlO4(001) substrates from FeSe0.5Te0.5 or FeSe0.5Te0.75 polycrystalline targets by pulsed…
Josephson scanning tunneling microscopy: A local and direct probe of the superconducting order parameter
Hikari Kimura, R. P. Barber, S. Ono +2
Direct measurements of the superconducting superfluid on the surface of vacuum-cleaved Bi2Sr2CaCu2O8(BSCCO) samples are reported. These measurements are accomplished via Josephson…
Hall effect in superconducting Fe(Se0.5Te0.5) thin films
I. Tsukada, M. Hanawa, S. Komiya +4
The Hall effect is investigated for eight superconducting Fe(Se_0.5_Te_0.5_) thin films grown on MgO and LaSrAlO_4_ substrates with different transition temperatures (T_c_). The no…
Deviation from the Wiedemann-Franz law induced by nonmagnetic impurities in overdoped La_{2-x}Sr_{x}CuO_{4}
X. F. Sun, B. Lin, X. Zhao +4
To investigate the validity of the Wiedemann-Franz (WF) law in disordered but metallic cuprates, the low-temperature charge and heat transport properties are carefully studied for…
Angle-Resolved Photoemission Spectroscopy of Iron-Chalcogenide Superconductor Fe1.03Te0.7Se0.3 : Strong-Coupling Superconductivity and Universality of Inter-Band Scattering
K. Nakayama, T. Sato, P. Richard +8
We have performed high-resolution angle-resolved photoemission spectroscopy of iron-chalcogenide superconductor Fe1.03Te0.7Se0.3 (Tc = 13 K) to investigate the electronic structure…
Extending Universal Nodal Excitations Optimizes Superconductivity in Bi2Sr2CaCu2O8+d
Aakash Pushp, Colin V. Parker, Abhay. N. Pasupathy +6
Understanding the mechanism by which d-wave superconductivity in the cuprates emerges and is optimized by doping the Mott insulator is one of the major outstanding problems in cond…
Diamagnetism and Cooper pairing above in cuprates
Lu Li, Yayu Wang, Seiki Komiya +4
In the cuprate superconductors, Nernst and torque magnetization experiments have provided evidence that the disappearance of the Meissner effect at is caused by the loss of l…
Measurement of x-ray absorption spectra of overdoped high-temperature cuprate superconductors: Inapplicability of the single-band Hubbard model
D. C. Peets, D. G. Hawthorn, K. M. Shen +9
X-ray absorption spectra on the overdoped high-temperature superconductors Tl_2Ba_2CuO_{6+delta} (Tl-2201) and La_{2-x}Sr_xCuO_{4+delta} (LSCO) reveal a striking departure in the e…
Characteristics of light reflected from a dense ionization wave with a tunable velocity
A. Zhidkov, T. Esirkepov, T. Fujii +3
An optically-dense ionization wave (IW) produced by two femtosecond laser pulses focused cylindrically and crossing each other is shown to be an efficient coherent x-ray converter.…
Boosted high harmonics pulse from a double-sided relativistic mirror
T. Zh. Esirkepov, S. V. Bulanov, M. Kando +2
An ultra-bright high-intensity X- and gamma-radiation source is proposed. A high-density thin plasma slab, accelerating in the radiation pressure dominant regime by a co-propagatin…
Pair breaking versus symmetry breaking: Origin of the Raman modes in superconducting cuprates
N. Munnikes, B. Muschler, F. Venturini +9
We performed Raman experiments on superconducting (Bi-2212) and (Y-123) single crystals. These results i…
