Unveiling the Superconducting Ground State of Heusler alloy Pd2ZrIn via muon spin relaxation and rotation measurement
Kavita Yadav, Anoop M Divakaran, Tsunehiro Takeuchi +1
Full Heusler alloys XInPd2 (X= Zr, Hf and Ti) have recently attracted significant attention owing to their symmetry-driven electronic structure and also due to the interplay betwee…
Momentum dependence of the energy gap in the superconducting state of optimally doped Bi2(Sr,R)2CuOy (R=La and Eu)
Y Okada, T Takeuchi, M Ohkawa +5
The energy gap of optimally doped Bi2(Sr,R)2CuOy (R=La and Eu) was probed by angle resolved photoemission spectroscopy (ARPES) using a vacuum ultraviolet laser (photon energy 6.994…
The influence of out-of-plane disorder on the formation of pseudogap and Fermi arc in Bi2Sr2-xRxCuOy (R=La and Eu)
Y. Okada, T. Takeuchi, A. Shimoyamada +2
We found that the length of the Fermi arc decreases with increasing out-of-plane disorder by performing angle resolved photoemission spectroscopy (ARPES) measurements in the superc…
The origin of the anomalously strong influence of out-of-plane disorder on high-Tc superconductivity
Y. Okada, T. Takeuchi, T. Baba +2
The electronic structure of Bi2Sr2-xRxCuOy(R=La, Eu) near the (pi,0) point of the first Brillouin zone was studied by means of angle-resolved photoemission spectroscopy (ARPES). Th…
On the determination of the Fermi surface in high-Tc superconductors by angle-resolved photoemission spectroscopy
J. Mesot, M. Randeria, M. R. Norman +13
We study the normal state electronic excitations probed by angle resolved photoemission spectroscopy (ARPES) in Bi2201 and Bi2212. Our main goal is to establish explicit criteria f…
Electronic Spectra and Their Relation to the (pi,pi) Collective Mode in High-Tc Superconductors
J. C. Campuzano, H. Ding, M. R. Norman +15
Photoemission spectra of Bi2Sr2CaCu2O8 reveal that the high energy feature near (pi,0), the "hump", scales with the superconducting gap and persists above Tc in the pseudogap phase…
Superconducting Gap Anisotropy and Quasiparticle Interactions: a Doping Dependent ARPES Study
J. Mesot, M. R. Norman, H. Ding +11
Comparing ARPES measurements on Bi2212 with penetration depth data, we show that a description of the nodal excitations of the d-wave superconducting state in terms of non-interact…
ARPES study of the superconducting gap and pseudogap in Bi2Sr2CaCu2O8+x
H. Ding, J. C. Campuzano, M. R. Norman +8
In this paper, we review some of our ARPES results on the superconducting and pseudo gaps in Bi2Sr2CaCu2O8+x. We find that optimally and overdoped samples exhibit a d-wave gap, whi…
Destruction of the Fermi Surface in Underdoped High Tc Superconductors
M. R. Norman, H. Ding, M. Randeria +8
The Fermi surface is a central concept in the theory of metals. Even though the optimally doped high temperature superconductors exhibit an anomalous normal state, angle resolved p…
