Abstract

Electronic and magnetic peculiarities of La2NiO4+δ are discussed emphasizing charge and spin ordering phenomena. Macroscopic measurements of conductivity (dc, optical) and magnetic susceptibility on samples of well-known oxygen stoichiometries agree to show anomalies where this peculiar ordering is expected. Our data account for the heterogeneous nature of the magnetism. The susceptibility which is quasi temperature independent in a large T range is modeled by a system of spins cluster.
