The structural, electrical transport and magnetic properties of perovskite oxides La1-xTexMnO3 (0.1 <= x <= 0.6) have been investigated and thus the magnetic phase diagram of La(1-x)TexMnO(3) (0.1 <= x <= 0.6) compounds as a function of temperature and the doping level x has been obtained. All samples have rhombohedral structure and undergo paramagnetic-ferromagnetic (PM-FM) transition accompanied with metal-insulator transition (MIT). A charge ordering (CO) transition begins to appear at T-CO similar to 250 K for the sample with x = 0.60. Moreover, the variation of the Curie temperature T-c and the MIT temperature T-p is quite complex and the results are discussed in terms of three factors including the average A-site cation radius (r(A)), the size mismatch sigma(2) and the Te content. In addition, there is an evidence for magnetoresistance (MR) at low-temperatures for all samples. (c) 2005 Elsevier B.V. All rights reserved.
