dc.description.abstractThe use of AC/DC magnetic susceptibility and impedance measurements to detect oxygen depletion effects in La0.7Ca0.3MnO3 +/-delta and NiMn2O4+delta spinel-type compounds is reported. For the NiMn2O4, for which no Mn4+ was found, three superposed Debye relaxations were observed in the range 260-180 K. Otherwise, in La0.7Ca0.3MnO3, the argon annealed has contributed to a decrease in T-C, but the amount of Mn4+ is still too high to allow the observation of a relaxation in this frequency window.
