Abstract

Weak ferromagnetism in Fe_1-xCo_xSb₂ is studied by magnetization and Mössbauer measurements. A small spontaneous magnetic moment of the order of ~ 10^-3µ_B 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.
