Tuning of magnetic and electronic states by control of oxygen content in lanthanum strontium cobaltites

S. Kolesnik, B. Dabrowski, J. Mais +4

We report on the magnetic, resistive, and structural studies of perovskite La${}_{1/3}$Sr${}_{2/3}$CoO${}_{3-\delta }$. By using the relation of synthesis temperature and oxygen partial pressu…
