Angle-resolved photoemission using the circularly polarized light in Pb-Bi2212

S. V. Borisenko, A. A. Kordyuk, A. Koitzsch +3

In a recent preprint Campuzano et al.(cond-mat/0309402), have questioned the validity of our ARPES results (cond-mat/0305179) contradicting the interpretation of earlier photoemiss…

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…

Temperature dependence of trapped magnetic field in MgB2 bulk superconductor

R. V. Viznichenko, A. A. Kordyuk, G. Fuchs +4

Based on DC magnetization measurements, the temperature dependencies of the trapped magnetic field have been calculated for two MgB2 samples prepared by two different techniques: t…

Doping dependence of the many-body effects along the nodal direction in the high-Tc cuprate (Bi,Pb)_2Sr_2CaCu_2O_8

A. Koitzsch, S. V. Borisenko, A. A. Kordyuk +5

Angle-resolved photoemission spectroscopy (ARPES) is used to study the doping dependence of the lifetime and the mass renormalization of the low energy excitations in the high-Tc c…

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…
