摘要：

Polycrystalline samples of K2Mg1-xCox(SO4)(2)center dot 6H(2)O (x = 0, 0.4) have been prepared by the slow evaporation method at room temperature. X-ray diffraction experiments confirmed the formation of pure crystalline picromerite. The electrical properties of the anhydrous compound K2Mg1-xCox(SO4)(2) have been studied by means of complex impedance spectroscopy in the temperature range 340-420 degrees C. The alternating current conductivity measurements exhibit features of the universal power law. Electric modulus properties of both pure and cobalt-doped picromerite have been investigated within a wide range of temperature and frequency.
