dc.description.abstractWe have been able to prepare ultrafine powders of pure and doped La Ca MnO (LCMO) at a relatively lower temperature of 5508C using a simple, cost effective and versatile PVA-based chemical route. A maximum magnetoresistance (MR) ratio of -25% is obtained at 20 K in a magnetic field of 3 kOe. Magnetoresistive behaviour being retained in the nanopowders may have implications for enhancing data storage capacity. The semicondutor-to-metal transition temperature, Tg however, shifts towards the lower temperature as p the particle size is reduced. To improve T and near-room-temperature MR additives like NH NO and citric acid have been used. In addition, Pb is substituted for Ca.en
