摘要：

The temperature-frequency dependences of the permittivity of crystals of lithium heptagermanate Li2Ge7O15 doped with Cr3+ ions are investigated. A dielectric response to reorientation of the dipole moments of the chromium impurity centers is revealed. Anomalies of the permittivity are described within the model of a Debye relaxator.
