The BaTiO3 nanoceramics were synthesized from nanopowders by means of low-temperature high pressure sintering. The structure and morphology of the BaTiO3 nanopowders and nanoceramics were investigated. Their magnetic properties were studied at the temperature range 1.72-300 K in magnetic fields up to 5 T. It was found that the BaTiO3 nanoceramic exhibits the paramagnetic behavior of the Curie-Weiss type in contrast to the nanopowder which is diamagnetic. (c) 2007 Elsevier B.V. All rights reserved.
