摘要：

We report the first observation of polar angular magnetoresistanee oscillations in the high-T-c cuprate Tl2Ba2CuO6. These measurements establish the existence of a coherent three-dimensional Fermi surface on the overdoped, superconducting side of the cuprate phase diagram, even in materials with extreme electrical anisotropy. Detailed analysis of the oscillations reveals that c-axis dispersion vanishes at specific symmetry points. This observation has implications for our understanding of a wide range of unusual metallic and superconducting properties of cuprates.
