Rongwei Hu, V. F. Mitrovic, and C. Petrovic
TL;DR
This study investigates how substituting Fe with Co in FeSb2 affects its magnetic and electronic properties, revealing transitions from semiconducting to metallic and magnetic states, with notable anisotropic transport and structural changes.
Contribution
It provides detailed insights into the anisotropic magnetic and transport behavior of Fe1-xCoxSb2 across different doping levels and structural phases.
Findings
FeSb2 becomes metallic and weakly ferromagnetic for x<0.5
Structural transition from orthorhombic to monoclinic with doping
Significant magnetoresistance and transport anisotropy observed
Abstract
Anisotropic magnetic and electronic transport measurements were carried out on large single crystals of Fe1-xCoxSb2 (0<= x <=1). The semiconducting state of FeSb2 evolves into metallic and weakly ferromagnetic by substitution of Fe with Co for x<0.5. Further doping induces structural transformation from orthorhombic Pnnm structure of FeSb2 to monoclinic P21/c structure of CoSb2 where semiconducting and diamagnetic ground state is restored again. Large magnetoresistance and anisotropy in electronic transport were observed.
