Epitaxial Nd1-xSrxNiO3 perovskite films grow by RF magnetron sputtering at 520-560 °C, while higher temperatures (620-670 °C) yield the Ruddlesden-Popper (Nd,Sr)2NiO4 phase plus NiO on SrTiO3(001).
By systematically controlling the growth temperature, we achieved the perovskite Nd1-xSrxNiO3 (NSNO) phase at 520 oC and 560 oC, as confirmed by HR- XRD

Epitaxial Sr-doped nickelate perovskite thin films and Ruddlesden-Popper phases grown by magnetron sputtering
Epitaxial Nd1-xSrxNiO3 perovskite films grow by RF magnetron sputtering at 520-560 °C, while higher temperatures (620-670 °C) yield the Ruddlesden-Popper (Nd,Sr)2NiO4 phase plus NiO on SrTiO3(001).
