The Berry phase is an important concept in solids, correlated to the bandtopology, axion electrodynamics and potential applications of topologicalmaterials. Here, we investigate the magnetotransport and Berry phase of rareearth element Gd doped Bi2Se3 (Gd_Bi2Se3) topological insulator at lowtemperatures and high magnetic fields. Gd_Bi2Se3 single crystals showShubnikov-de Haas (SdH) oscillations with nontrivial Berry phase while Bi2Se3single crystals show zero Berry phase in SdH oscillations. The temperaturedependent magnetization curves can be well fitted with the Curie-Weiss law in3-300 K region, indicating no magnetic ordering in Gd_Bi2Se3 crystals.Moreover, Gd doping has limited influence on the quantum oscillation parameters(e.g., frequency of oscillations, the area of the Fermi surface, effectiveelectron mass, Fermi wave vectors etc.), but has an impact on the Hallmobility, carrier density, and band topology. Our results demonstrate that Gddoping can tune the Berry phase of topological insulators effectively, whichmay pave a way for the future realization of many predicted exotic transportphenomena of topological origin.
