Nuclear magnetic resonace (NMR), EPR and magnetization measurements in NaxCoO2 for 0.65less than or equal toxless than or equal to0.75 are presented. While the EPR signal arises from Co4+ magnetic moments ordering at T(c)similar or equal to26 K, Co-5

The electrical conductivity of lithium-manganese spinels is analyzed in samples with different starting Li cationic fraction x. Li-rich spinels, resulting from Li-Mn substitution around the stoichiometric value (x = 0.333), show conductivity values h
