Abstract
New mixed transition and alkali metal sulfides ACuZnS(2) (A = K, Rb) and Ba KCu3ZnS4 with ThCr2Si2 structure were synthesized by the sulfidation of mix tures of stoichiometric quantities of alkali and alkaline-earth metal carbo nates, copper metal, and zinc oxide, and their electric and magnetic proper ties were studied. According to the results of resistivity measurements, ne w compounds are semiconductors with a room-temperature resistivity of rho ( RT) similar to 10(-2) Omega cm. The temperature dependence of magnetic susc eptibility shows a temperature-independent paramagnetic behavior in the cas e of ACuZnS(2) (A = K, Rb) and a Curie-type behavior in the case of BaKCu3Z nS4.
