|Abstract:||Three compositions of sodium substituted lanthanum manganites La₁₋xNaxMnO₃ (for x = 0.1, 0.2 and 0.5) have been prepared using sol-gel technique followed by two different thermal treatments. Attempts to prepare 50 atomic per cent Na (for La) substituted sample, which would be the maximum permissible amount of Na as per valence consideration, did not yield a compound of correct stoichiometry. Of the two stoichiometric samples, the one with 20 atomic% sodium shows an ordered ferromagnetic state and that with 10 atomic% sodium is disordered ferromagnet.|
