摘要：

Electromagnetic response of CuIr2S4 at 34 GHz has been measured by a cavity perturbation method. Clear anomalies appear in the temperature dependences of the resonant frequency and the full-width at half-maximum of the Q-curves at the metal-insulator phase transition. These anomalies of the microwave responses are very suggestive of a simultaneously charge-ordering phase transition with the metal-insulator phase transition of CuIr2S4.
