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 the present study, glasses with composition (80-X) ร B 2 O 3 ร XBi 2 O 3 ร 20Fe 2 O 3 (X ยผ 10, 15 and 20 mol%) have been prepared by the conventional melt quenching technique. The glassy state of the samples is characterized using DTA and X-ray diffraction. The infrared spectra of these glasses a
The reaction of Fe(BF 4 ) 2 โข6H 2 O and one equivalent of HC(3,5-Me 2 pz) 3 in acetonitrile leads to the formation of {Fe[HC(3,5-Me 2 pz) 3 ](H 2 O) 3 }(BF 4 ) 2 . The solution phase 1 H NMR spectrum is broad with chemical shifts ranging from 54 to -42 ppm, a range that is indicative of a paramagnet
