Abstract

Crystal structures and magnetic properties of Sr₂Fe(Mo_1-XNb_-X)O₆ with x=0.0-1.0 were studied by x-ray diffraction and magnetic susceptibility measurement. The Sr₂Fe(Mo_1-XNb_-X)O₆ solid solutions with x=0.0-0.6 have ordered arrangement of B site cations, (Mo, Nb)⁵⁺ and Fe³⁺, and transform to the ferrimagnetic state below their Curie temperatures. The samples with x=0.7-1.0 have disordered arrangement of B site cations and transforms to a spin glass state around 30K.
