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
Chemical and structural properties of the system (1 -x)Fe203 -4-xNd203, 0 \_< x<\_ 1, were investigated using X-ray diffraction, 57Fe M6ssbauer spectroscopy and Fourier transform-infrared (FT-IR) spectroscopy. The samples were prepared by the chemical coprecipitation and thermal treatment of Fe(OH)3
