摘要

The crystal structure and physical properties of the Sr ₂FeMO₆ (M = Mo, W) double perovskite have been investigated. Analysis of the X-ray powder diffraction pattern based on Rietveld refinement indicates that Sr₂FeMoO₆ and Sr ₂FeWO₆ have tetragonal cell (space group: I4/m) and orthorhombic cell (space group: Immm), respectively. The Curie-Weiss fit for Sr₂FeWO₆ gives Curie constant, C = 6.08 and Weiss temperature, θ = -32.6 K. The small and negative value of θ suggests the existence of both weak ferromagnetic and antiferromagnetic interactions at low temperature. The antiferromagnetic interaction dominates over the weak ferromagnetic one.
