The oxygen nonstoichiometry of La 2؊x Sr x CuO 4؊ (x ‫؍‬ 0-0.3) was measured as a function of Sr content, temperature (400-1000°°C), and oxygen partial pressure (P(O 2 ‫؍)‬ 1-1؋10 ؊10 atm) using high-temperature gravimetry and coulometric titration. The oxygen nonstoichiometry ranges from oxygen exc
