Abstract: Abstract: We have successfully prepared a single-phase Ce-doped sample (La0.56Ce0.14)Sr0.30MnO3 by a solid-state route, without CeO2 oxide segregation. Compared to the undoped sample La0.70Sr0.30MnO3, the structure remains hexagonal with space group without a large variation of the cell parameters and volume. The thermal variation of the magnetization shows that the Ce-doped sample exhibits a ferromagnetic to paramagnetic transition at 357K and an anti-ferromagnetic coupling below 100K between the ferromagnetic Mn moments and the Ce moments and thus form a ferrimagnetic ground state. Comparing our results to those of the literature, we can suggest that the cerium ions are in a trivalent state (Ce3+) and the anomalous behaviour attributed to a Kondo-like effect.
