我们研究了Fe_(1-x)$Cr_(X)$Sb_(2})($0leq xleq 1$)单晶的磁输运和电输运性质的各向异性。随着Fe逐渐被Cr取代，体系的磁性基态由顺磁向反铁磁演化。电输运中的各向异性随着铬替代量的增加而减小，并且消失了$x=0.5$。我们发现，在0.4leq×0.75美元的低温下，可变距离跳跃(VRH)传导机制占主导地位。
We have investigated anisotropy in magnetic and electrical transport properties of Fe$_{1-x}$Cr$_{x}$Sb$_{2}$ ($0leq xleq 1$) single crystals. The magnetic ground state of the system evolves from paramagnetic to antiferromagnetic with gradual substitution of Fe with Cr. Anisotropy in electrical transport diminishes with increased Cr substitution and fades away by $x=0.5$. We find that the variable range hopping (VRH) conduction mechanism dominates at low temperatures for $0.4leq xleq 0.75$.
