Magnetic and electrical transport properties of Fe$_{1-x}$Cr$_{x}$Sb$_{2}$
ORAL
Abstract
We have investigated magnetic, thermodynamic and electrical transport properties of Fe$_{1-}$xCr$_{x}$Sb$_{2}$ (0$\le $x$\le $1) single crystals. Ground state of the system evolves from nonmagnetic semiconductor for x = 0 to antiferromagnetic semiconductor for x = 1. In contrast to Co substitution, Cr doping in FeSb$_{2}$ does not result in metallic state and magnetoresistance is negligible. Magnetic phase diagram and conduction mechanism will be discussed.
