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 Nd${}_{2-x}$Ce${}_x$CuO${}_4$ at different doping levels by means of magnetoresistan…
