摘要：

Gigantic negative magnetoresistance (MR) reaching 80% in a field of 30 kOe is detected in semiconductive spin glasses Cu2/3Ge1/3Cr2S4 and Cu0.5In0.5Cr2Se4. In the temperature dependence of the MR a sharp minimum is observed at the freezing temperature estimated by the maximum nonlinear magnetic susceptibility.
