Bulk electronic structure of the antiferromagnetic superconducting phase in ErNi2B2C
T. Baba, T. Yokoya, S. Tsuda +15
We have performed temperature (T) - dependent laser-photoemission spectroscopy of antiferromagnetic (AF) superconductor ErNi2B2C to study the electronic-structure evolution reflect…
Evidence for two energy scales in the superconducting state of optimally doped (Bi,Pb)2(Sr,La)2CuO6+d
Takeshi Kondo, Tsunehiro Takeuchi, Adam Kaminski +2
We use angle-resolved photoemission spectroscopy (ARPES) to investigate the properties of the energy gap(s) in optimally doped (Bi,Pb)2(Sr,La)2CuO6+d (Bi2201). We find that the spe…
Low-Energy Charge-Density Excitations in MgB: Striking Interplay between Single-Particle and Collective Behavior for Large Momenta
Y. Q. Cai, P. C. Chow, O. D. Restrepo +12
A sharp feature in the charge-density excitation spectra of single-crystal MgB, displaying a remarkable cosine-like, periodic energy dispersion with momentum transfer () a…
Carbon-substitution dependent multiple superconducting gap of MgB: a "sub-meV" resolution photoemission study
S. Tsuda, T. Yokoya, T. Kiss +10
``Sub-meV'' resolution photoemission spectroscopy was used to study carbon-substitution dependence on the multiple superconducting gap of Mg(BC. Two features c…
Bulk Electronic structure of NaCoO.1.3HO
A. Chainani, T. Yokoya, Y. Takata +18
High-energy (h = 5.95 keV) synchrotron Photoemission spectroscopy (PES) is used to study bulk electronic structure of NaCoO.1.3HO, the layered superconducto…
Definitive experimental evidence for two-band superconductivity in MgB2
S. Tsuda, T. Yokoya, Y. Takano +5
The superconducting gap of MgB2 has been studied by high-resolution angle-resolved photoemission spectroscopy (ARPES). The momentum(k)-resolving capability of ARPES enables us to i…
