立方钙钛矿结构稳定在SrFeO 3和SrNiO 3的固溶体中。这些化合物是通过高压合成得到的，在共角氧八面体中含有高价态的Fe和Ni离子。SrFe 1-xNixO 3（x = 0.4和0.5）在室温下表现出类似铁磁的行为，而端元钙钛矿SrFeO 3（x = 0）具有螺旋反铁磁性（TN = 134 K）。Ni替代立方反铁磁SrFeO_3中的Fe，产生铁磁性。
The cubic perovskite structure was stabilized in solid solution of SrFeO3 and SrNiO3. The compounds were obtained by high pressure synthesis and contained high valence state of Fe and Ni ions in the corner-sharing oxygen octahedra. SrFe1-xNixO3 with x = 0.4 and 0.5 showed ferromagnetic-like behaviors at room temperature, in contrast to the end member perovskite SrFeO3 (x = 0) with helical antiferromagnetism (TN = 134 K). Ni substituton for Fe in the cubic antiferromagnetic SrFeO3 induced the ferromagnetism.
