Weak ferromagnetism in Fe1-x Cox Sb2 is studied by magnetization and Mössbauer measurements. A small spontaneous magnetic moment of the order of ∼ 10-3 μB appears along the b axis for 0.2≤x≤0.4. Based on a structural analysis, we argue against extrinsic sources of weak ferromagnetism. We discuss our results in the framework of the nearly magnetic electronic structure of the parent compound FeSb2.
