Resumen/Abstract

Data are presented on the thermal dependence of the hysteretic properties of cationic vacancies including manganite samples of composition LaMnO3+[delta] ([delta] = 0,05 and 0.12). Our results evidence the presence in both samples of two magnetic phases having ferro- and antiferromagnetic orders, respectively. The temperature dependence of the coercivity and relaxational properties of the samples is closely linked to the connectivity of the magnetic moment bearing Mn3+ -Mn4 + ferromagnetic clusters that demagnetize independently in the case of the [delta] = 0.05 sample and collectively in that of the [delta] = 0.12 one, as evidenced from the activation volume results ([delta] = 0.05) which yielded a size of the same order magnitude as that obtained in previous works for the Mn3+ - Mn4 + ferromagnetic cluster size.
