| 摘 要： | The resistivity and magnetization for the CuIr2（S1-xTex）4 （0≤x≤ 0.10） system are investigated. Compared with the Se doping, the substitution of Te for S leads to stronger suppression on the metal-insulator transition. Vacancies and imperfections in the sample lattice are found to modify the magnetization, which can be qualitatively understood to consist of the Pauli paramagnetism, Landau diamagnetism, Larmor diamagnetism and Curie magnetism contributions.
