摘要：

The dielectric response of valence fluctuation compound Sm3Se4 has been measured in the frequency range from 20 Hz up to 1 GHz. The resultant response of Sm3Se4 is described by a superposition of two independent dispersions with the Cole-Cole type, which are given by the valence fluctuating state in Sm3Se4 crystal with vacancies. The phase angle 0=90-degrees for the admittance of Sm3Se4 at low temperatures leads the absence of free carrier like in an ideal capacitor. Similar behavior on Sm2Se3 is also presented.
