EPR and dielectric spectroscopy of reorienting Cr<sup>3+</sup>-Li<sup>+</sup> pair centres in Li<sub>2</sub>Ge<sub>7</sub>O<sub>15</sub> crystal
Earlier it has been shown that in the lithium heptagermanate Li<sub>2</sub>Ge<sub>7</sub>O<sub>15</sub> structure the chromium doping ions substitute the germanium hosts and create Cr<sup>3+</sup>-Li<sup>+</sup> pair centres. In the paper E...

| description | Earlier it has been shown that in the lithium heptagermanate Li<sub>2</sub>Ge<sub>7</sub>O<sub>15</sub> structure the chromium doping ions substitute the germanium hosts and create Cr<sup>3+</sup>-Li<sup>+</sup> pair centres. In the paper EPR and dielectric spectra of Li<sub>2</sub>Ge<sub>7</sub>O<sub>15</sub>:Cr<sup>3+</sup> crystal are studied in the temperature range 300-500 K. The thermally activated reorientation of Cr<sup>3+</sup>-Li<sup>+</sup> pairs has been detected through EPR line width broadening and dielectric relaxation. |
