Abstract
Co(x)Cd(1-x)C(2)O(4)4H(2)O crystals grown by gel technique are charact erized for dielectric properties by optical absorption measurements. L oss curve shows a relaxation peak at 500 KHz corresponding to a relaxa tion time of 0.3 mu s. Cole-Cole diagrams give exponent of universal p ower law to be equal to 0.22. Optical absorption shows peaks due to Co +2 ion and water of hydration. An attempt is made to understand the re sults.
