We study the influence of ruthenium doping on electric and magnetic properties of Ca_0,6Pr_0,4Mn_1-yRu_yO₃ (y = 0,0; 0,03;0,05; 0,07) perovskite prepared by solid state reaction method. The ZFC and FC thermomagnetic, magnetization measurements indicate the increasing tendency of ferromagnetism due to ruthenium doping.The charge ordering phenomenon observed at T_CO ~ 291K in Ca_0,6Pr_0,4MnO₃ sample. Temperature dependence of resistivity cure is depressed with increasing Ru amount.The variable range hopping nature of sample’s conductivity is discussed.
