Crystal and Magnetic Structures of Sr2Fe2O5 at Elevated Temperature

Peculiarities of layered perovskite-related GdSrFeO4 compound solid state synthesis

“…This fact is confirmed by results, demonstrated at [28,29]. So, for example, SrFeO 3−ı oxide as is pointed out at [30] was synthesized by calcination of initial oxides under 1000 • C in air. Subject to [29] Sr 4 Fe 6 O 13 compound was the member of layered perovskite-related compounds and was formed and stable at 775-1225 • C temperature region.…”

Magnetic and electric field induced resistance change in SrFeO thin film

“…The negative MR effect in mainly tetragonal materials has been confirmed for a ceramic sample of SrFeO 3−X by Srinath et al [8]. SrFeO 2.5 has brownmillerite structure with orthorhombic [9] and SrFeO 2 in more advanced oxygen deficiency compared with SrFeO 2.5 is tetragonal [10]. In the results of I-V property, we observed NDR which is evidence of oxygen migration.…”

Preparation of SrFeO∼2.85 perovskite using a citric acid assisted Pechini-type method

“…These values are consistent with the data reported in the literature [37,38] for the perovskite of the type SrFeO x (2.5 ≤ x ≤ 3.0). Fig.…”
