Heusler合金，${\mathrm{Co}}_{2}\mathrm{Cr}\mathrm{Al}$，是一种巡回磁铁，订购温度为$T= 333\phantom {\rule{0.3em}{0 ex}}\mathrm{K}$。我们测量了从室温到低温的温度依赖的反常霍尔效应和磁电阻。磁电阻是正的并且非常小。反常霍尔电导率跟随磁化强度，在整个温度范围内两个量的比率是恒定的，这表明反常霍尔效应的起源是内在的。
The Heusler alloy, ${\mathrm{Co}}_{2}\mathrm{Cr}\mathrm{Al}$, is an itinerant magnet that orders at $T=333\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. We have measured its temperature-dependent anomalous Hall effect and magnetoresistance from room temperature down to low temperatures. The magnetoresistance is positive and very small. The anomalous Hall conductivity follows the magnetization with the ratio of the two quantities being constant over the whole temperature range, suggesting that the origin of the anomalous Hall effect is intrinsic.
