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
In 2 O 3 crystallizes in the bixbyite, or C-type rare earth, structure (space group Ia3), as do the smaller lanthanide oxides (Tb+Lu) and the oxides of Y and Sc. Solid solutions of In 2Ψx M x O 3Ψ (M β«Ψβ¬ Y or Sc) with varying lattice parameters were prepared and doped with tin. Substitution of tin o
