The synthesis of pure and Cr-doped nanosized LiMn 2 O 4 particles has been carried out by solid-state process on high-energy ground mixtures. In situ X-ray analysis demonstrates the spinel forms as single phase at 623 K passing through the Mn 3 O 4 p

The crystal structures of BaTbO 3 have been investigated over a wide temperature range between 40 and 773 K using high-resolution time-of-flight neutron powder diffraction. Two-phase transitions were observed. Below about 280 K, BaTbO 3 adopts an ort
