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. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2011
