Fe1-xCrxSb2磁、电输运性质的各向异性

Anisotropy in the magnetic and electrical transport properties of Fe1-xCrxSb2

Rongwei Hu, V. F. Mitrovic, C. Petrovic

摘要:

本文研究了Fe_(1-x)Cr_xSb_2(0<= x <=1)单晶的磁输运和电输运性质的各向异性。随着Cr逐渐取代Fe,系统的磁基态由顺磁向反铁磁演化。电输运中的各向异性随着Cr取代的增加而减小,并在x=0.5时消失。我们发现,在0.4<= x <=0.75的低温下,变程跳跃(VRH)导电机制占主导地位。

英文摘要:

We have investigated anisotropy in magnetic and electrical transport properties of Fe1-xCrxSb2 (0<= x <=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 0.4<= x <=0.75.
