Structural Characterization and Physical Properties of LiMMnO4 (M: Cr, Ti)
? The title compounds are synthesized from stoichiometric mixtures of either
14- 015 Spinels.
Li2CO3, MnCO3�5H2O, and TiO2 at 1173 K for M: Ti or LiNO3, Cr(NO3)3�2O, and
MnO2 at 1223 K for M: Cr. Neutron diffraction results reveal that both compounds crystallize in the space group Fd3m. Both compounds show semiconducting behavior.
Magnetic data indicate that no long-range magnetic ordering is present, suggesting a
spin-glass transition for M: Cr at low temperature, while for M: Ti the presence of
non-magnetic ions in the octahedral sublattice provokes an inherent magnetic frustration. ? (ARILLO*, M. A.; CUELLO, G.; LOPEZ, M. L.; MARTIN, P.; PICO, C.;
