Strategies for optimizing the single GdSrFeO4 phase synthesis
Open Chemistry, 2023 This work provides data on strategies for single GdSrFeO4 phase solid state synthesis. Earlier works have shown that under the solid-state synthesis conditions, the GdSrFeO4 preparation is hampered by the formation of non-target product: Gd2SrFe2O7. This
