perovskite, varying the conventional route by solid-state reaction method, and the AGD was employed in decarbonizing, annealing, and sintering steps. Structural characterization was carry out by the Rietveld refinement of X-ray diffraction on samples after sintering step at room temperature. Magnetic properties were analyzed through magnetization curves as a function of temperature for applied magnetic field of 1 kOe by the zero-field-cooled-field-cooled method. CaMn

perovskite was also produced by conventional method in resistive furnace, and its behavior was compared with these obtained for samples AGD produced. The X-ray analysis reveals that samples crystallize in a P nma structure. The magnetization measurements allow analyzing the behavior of the sample, at low temperatures, and comparing the magnetic transitions in the samples produced by both the methods. The results show that AGD can be an alternative to produce these ceramic materials with an important reduction in the production time with respect to conventional method.
