    AnnotationThe half-doped manganites Pr0.5Ca0.5MnO3 and La0.5Ca0.5MnO3 have been studied by structural and magnetic methods. Though the room temperature structure is not affected by the nanosize form, the charge ordering transition, common for bulk systems, is not developed at low temperatures. This different behaviour is explained by effects of the particle surface.
