Synthesis, structural and magnetic properties of spin ladder compound Ca1−xCoxCu2O3

► Powder sample of (Ca1−xCox)Cu2O3 (x=0.00-1.00) has been synthesized by the solid state reaction method for the first time. ► DC magnetic susceptibility χ(T) results of CaCu2O3 and CoCu2O3 show antiferromagnetic shift (TN) at 27 and 215 K in that order. ► χ(T) of CoCu2O3 shows a broad transition with the peak temperature around 215 K.
