Interdependence of magnetism and superconductivity in the borocarbide TmNi2B2C
K. Noergaard, M. R. Eskildsen, N. H. Andersen +4
We have discovered a new antiferromagnetic phase in TmNi2B2C by neutron diffraction. The ordering vector is Q_A = (0.48,0,0) and the phase appears above a critical in-plane magneti…

Quasiparticle bands and superconductivity in bilayer cuprates
A. I. Liechtenstein, O. Gunnarsson, O. K. Andersen +1
We analyze the generic features of the energy spectrum for two coupled CuO layers with a realistic extended Hubbard model. The quasiparticle bands exhibit flat regions near X(Y…
