Abstract
Several La0.5Ca0.5MnOy samples with identical oxygen content have been prep ared by two different routes. Magnetic measurements show that their propert ies are strongly dependent on the synthesis method even for materials with the same anionic composition. A charge ordering state is reported for anion ic deficient samples with 40% of Mn4+. The role of Ca in such a behavior is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
