Lithium-rich lanthanide oxides Li{sub 8}PrO{sub 6} and Li{sub 8}TbO{sub 6} were prepared and their magnetic properties were studied. The effective magnetic moments for the praseodymium and terbium ions and the observation of their electron paramagnetic resonance (EPR) spectra show that the lanthanide ions are in the tetravalent oxidation state in these compounds. The low effective magnetic moment for the Pr{sup 4+} ion in the Li{sub 8}PrO{sub 6} corresponds to the low g value measured from the EPR measurement. The observation of the EPR spectrum at room temperature strongly shows that the terbium ion is in the S ground state, i.e., in the tetravalent state.
