Abstract
We report on semiclassical angle-dependent magnetoresistance oscillations and the Shubnikov–de Haas effect in the electron-overdoped cuprate superconductor Nd2-xCexCuO4. Our data provide convincing evidence for magnetic breakdown in the system. This shows that a reconstructed multiply connected Fermi surface persists, at least at strong magnetic fields, up to the highest doping level of the superconducting regime.
