Abstract
We have investigated structural, magnetic, and transport properties of $\text{Fe}{({\text{Sb}}_{1\ensuremath{-}x}{\text{Te}}_{x})}_{2}$ single crystals. Whereas metallic ground state is induced for $x=0.001$, canted antiferromagnetism is observed for $0.1\ensuremath{\le}x\ensuremath{\le}0.4$ with an intermediate ferromagnetic phase for $x=0.2$. With higher Te doping, semiconducting behavior is restored and the variable range hopping conduction mechanism dominates at low temperatures for $0.4\ensuremath{\le}x\ensuremath{\le}0.6$. We discuss our results within the framework of inverted metal to insulator in correlated electron insulators.
