Description
Quantitative microstructural information is obtained on the nonequilibrium cation arrangement in high-energy milled MgAl2O4, ZnFe2O4, and NiFe2O4 by means of 27Al MAS-NMR, XPS, and 57Fe Moessbauer spectroscopy, respectively. Independently of the ionic configuration in the nonactivated materials, the mechanically induced redistribution of cations was found to be directed towards the random arrangement. The cation inversion parameter of the nanosized milled spinels is compared with that of the bulk materials at high temperatures
