Circular dichroism and bilayer splitting in the normal state of underdoped (Pb,Bi)Sr(CaY)CuO and overdoped (Pb,Bi)SrCaCuO
S. V. Borisenko, A. A. Kordyuk, S. Legner +11
We report an ARPES investigation of the circular dichroism in the first Brillouin zone (BZ) of under- and overdoped Pb-Bi2212 samples. We show that the dichroism has opposite signs…
Evidence for CuO conducting band splitting in the nodal direction of Bi-2212
A. A. Kordyuk, S. V. Borisenko, A. N. Yaresko +12
Using angle-resolved photoemission spectroscopy with ultimate momentum resolution we have explicitly resolved the bilayer splitting in the nodal direction of Bi-2212. The splitting…
Diagonal Antiferromagnetic Easy Axis in Lightly Hole Doped Y_{1-x}Ca_xBa_2Cu_3O_6
Andras Janossy, Titusz Feher, Andreas Erb
Hole induced changes in the antiferromagnetic structure of a lightly Ca doped Gd:Y_{1-x}Ca_xBa_2Cu_3O_6 copper oxide single crystal with x~0.008 is investigated by Gd3+ electron sp…
Circular dichroism in angle-resolved photoemission spectra of under- and overdoped Pb-Bi2212
S. V. Borisenko, A. A. Kordyuk, A. Koitzsch +7
We use angle-resolved photoemission with circularly polarized excitation to demonstrate that in the 5x1 superstructure-free Pb-Bi2212 material there are no signatures of time-rever…
