Description
Copper doped, CaMn1-xCu xO3 compounds have been prepared in single phase form for x = 0-0.20. XRD patterns could be analyzed using Pbnm space group with typical lattice parameters a = 5.276 A, b = 5.259 A and c = 7.459 A. All samples exhibit antiferromagnetic transitions with Neel temperatures around 124 K. The temperature variations of electrical resistivity follow the semi-conducting behaviour and they could be analyzed using variable range hopping with Coulomb interaction (ES-VRH) model. The Cu doping is found to enhance the antiferromagnetic interactions
