Abstract

EPR and magnetization measurements of La2NiO4 samples prepared by two different methods are discussed. From the comparison with magnetization and EPR properties of metallic nickel it can be concluded that the sample prepared by the ceramic method is contaminated with ∼ 1% of metallic nickel whereas no evidence of contamination is found in a sample prepared by the so-called liquid-mix technique.
