An in situ Raman spectroscopic study was conducted to investigate the pressure-induced phase transformation in the synthetic ZnCr 2 O 4 spinel up to pressures of 70 GPa at room temperature. Results indicate that ZnCr 2 O 4 spinel starts to transform to the CaFe 2 O 4 (or CaTi 2 O 4 ) structure at 17
## Abstract theoretical study
Lithium manganese spinel Li 1 Ψ y Mn 2 Ψ y O 4 (0.04y40.07) synthesized by the sol+gel process is studied with a focus on the e4ects of the changes of formation conditions which can sensibly determine the mean crystallite size from a few nanometers to several hundred nanometers. Changes of stoichiom
