Abstract
In this work, we report the production of new composite perovskite manganite system CaMn ,Ti,O, with doping x = 0.25, 0.5 and 0.75, reaction sintering method solid state. Structural characterization was performed using the technique of X-ray Diffraction (XRD) and the Rietveld method, obtaining a tetragonal structure, with Prima spatial group (# 62) (a=5.3586a y a=5.2997A: b=7.5041 A y b=7.5526a; c+5.3l82& y c=5.3278A). In this paper takes the discussion on possible structural changes with changes in the system titanium CaMn, ,Ti,O,.
