| Abstract: | The permittivity ? of the molecular complexes (BTX)C60CS2, (DAN)C60(C6H6)3, and (S4N4)1.2C60(C6H6)0.8 has been studied at 100 MHz. A maximum has been observed to appear in the temperature dependence ?(T) at T≈90 K, which can be assigned to freezing of the orientational disorder. A region of anomalous growth of ? with decreasing temperature has been found in the low-temperature range T≤25 K, this feature being apparently sensitive to the actual packing pattern of C60 spheres in the molecular complex. |
