The magnetic properties of a-Fe 2 O 3 nanoparticles of different shapes (spherical, rhombohedral and acicular), prepared as powders by a chemical route, have been investigated. The particle size effect on the Morin transition (T M = 263 K in the bulk system) have been studied by analyzing the temper
