, "Gamma-irradiation effects on the electrical conductivity of some two dimensional complexes: RMnCl4, RCoCl4 and RMn0.5Co0.5Cl4; {Mathematical expression}", Journal of Radioanalytical and Nuclear Chemistry Letters, vol. 135, no. 2: Kluwer Academic Publishers, pp. 99-109, 1989. AbstractWebsite

DTA, dc-conductivity and thermoelectric power of the compounds RMnCl4, RCoCl4 and RMn0.5Co0.5Cl4; {Mathematical expression}, have been measured over a temperature range of 300-500 K. Both DTA and dc-conductivity results showed the presence of many phase transitions in each one of the complexes investigated. The conductivity results were explained in terms of an electron hopping mechanism. The effect of γ-irradiation on the conductivity data and the type of crystal phases have been investigated and discussed. © 1989 Akadémiai Kiadó.
