Fermi Surface Evolution in an Electron-Doped High-Tc Superconductor Revealed by Magnetic Quantum Oscillations

T. Helm, M. V. Kartsovnik, M. Bartkowiak +5

We report on the direct probing of the Fermi surface in the bulk of the electron-doped superconductor NdCeCuO at different doping levels by means of magnetoresistan…

Morphology of the Superconducting Vortex Lattice in Ultra-Pure Niobium

S. Mühlbauer, C. Pfleiderer, P. Böni +5

The morphology of the superconducting flux line lattice (FLL) of Nb comprises gradual variations with various lock-in transitions and symmetry breaking rotations. We report a compr…

On the contribution of nearly-critical spin and charge collective modes to the Raman spectra of high-Tc cuprates

S. Caprara, C. Di Castro, T. Enss +1

We discuss how Raman spectra are affected by nearly-critical spin and charge collective modes, which are coupled to charge carriers near a stripe quantum critical point. We show th…
