Abstract

Samples of

{La}_{2}

O_{4}

prepared with a nominal stoichiometry slightly deficient in lanthanum (i.e.,

{La}_{1.9}

O_{4}

) show a greater diamagnetic susceptibility and a sharper resistive transition than samples prepared from stoichiometric amounts of starting materials. The effect of adding

K_{2}

O_{3}

to the reaction mixture is also discussed.
