摘要： A solid oxide fuel cell, which converts a chemical reaction between a fuel and air or oxygen into electric energy, and which is constructed by a solid electrolyte, an air electrode mounted adjacent to the solid electrolyte, a fuel electrode, and an inter-connector for connecting with other cell units is provided. The air electrode of the above fuel cell is made of a perovskite-type oxide material with a composition expressed by LnNi.sub.1-x Fe.sub.x O.sub.3 and YNi.sub.1-x Fe.sub.x O.sub.3 and wherein Ln represents lanthanide elements and x is in a range of 0.30 to 0.60. The perovskite-type oxide materials containing nickel and iron satisfy requirements to provide higher electronic conductivity than the conventional material and closer thermal expansion coefficient to that of the solid electrolyte than that of the conventional air electrode material.

摘要： .gamma.-Fe.sub.2 O.sub.3 film added at least one selected from the group consisting of Pd, Au, Pt, Rh, Ag, Ru, Ir, Os as additive, especially Os are disclosed. Reduction from .alpha.-Fe.sub.2 O.sub.3 to Fe.sub.3 O.sub.4 is accelerated by additive Os to accompany to a uniform reduction and increased the ratio of magnetic phase in the film. .gamma.-Fe.sub.2 O.sub.3 film medium added Os improves the saturation magnetization and increases the coercive force in proportion to amount of additive Os. Application of an external field to said film introduced magnetic anisotropy into said film, therefore said film medium improves coercive force and squareness of hysteresis loop by the grant of anisotropy. .gamma.-Fe.sub.2 O.sub.3 crystal grain is prepared by additive Os to obtained fine grain.

摘要翻译： 公开了添加了选自Pd，Au，Pt，Rh，Ag，Ru，Ir，Os中的至少一种作为添加剂的γ-Fe 2 O 3膜。 通过添加剂Os可以促进从α-Fe2O3向Fe3O4的还原，从而均匀地还原并增加膜中磁相的比例。 添加的γ-Fe2O3膜介质可以提高饱和磁化强度，并且与添加剂的量成比例地增加矫顽力。 对所述膜施加外部场，将磁各向异性引入所述膜，因此所述膜介质通过赋予各向异性来提高磁滞回线的矫顽力和矩形度。 通过添加剂Os制备γ-Fe 2 O 3晶粒以获得细晶粒。 所得的γ-Fe2O3薄膜介质会降低噪音。
