Magnetic order in lightly doped cuprates: Coherent vs. incoherent hole quasiparticles and non-magnetic impurities
Marijana Kircan, Matthias Vojta
We investigate magnetic properties of lightly doped antiferromagnetic Mott insulators in the presence of non-magnetic impurities. Within the framework of the t-J model we calculate…
Absence of an isotope effect in the magnetic resonance in high- superconductors
S. Pailhès, P. Bourges, Y. Sidis +4
An inelastic neutron scattering experiment has been performed in the high-temperature superconductor to search for an oxygen-isotope shift of the well-known…
Novel Josephson Effect in Triplet Superconductor - Ferromagnet - Triplet Superconductor Junctions
Boris Kastening, Dirk K. Morr, Dirk Manske +1
We predict a novel type of Josephson effect to occur in triplet superconductor - ferromagnet - triplet superconductor Josephson junctions. We show that the Josephson current, I_J,…
Influence of Pressure on the Structure and Electronic Properties of the Layered Superconductor Y2C2I2
Kyungsoo Ahn, Reinhard K. Kremer, Arndt Simon +3
The structural properties under hydrostatic pressure up to 3 GPa of the layered rare earth carbide halide superconductor Y2C2I2 are studied by neutron powder diffraction at room te…
Band filling and interband scattering effects in MgB: C vs Al doping
Jens Kortus, Oleg V. Dolgov, Reinhard K. Kremer +1
We argue, based on band structure calculations and Eliashberg theory, that the observed decrease of of Al and C doped MgB samples can be understood mainly in terms of a b…
