标题： Comment on "Correlation between Bulk Thermodynamic Measurements and the Low-Temperature-Resistance Plateau in SmB6"

摘要： 低温电阻平台在$\rm SmB_6$单晶中被观察到，这已被电输运测量证实是由于表面而非体导电。 最近，已经研究了$\rm SmB_6$中体热力学测量与低温电阻平台之间的相关性，并通过X射线吸收光谱和X射线磁圆二色性获得了表面Sm价态的变化。 在这里，我们表明报告中的陈述并未得到X射线吸收光谱和X射线磁圆二色性的结果支持。 显示英文摘要

摘要： Low-temperature-resistivity plateau observed in $\rm SmB_6$ single crystal,which is due to surface, not bulk, conduction has been confirmed from electrical transport measurements. Recently, the correlation between bulk thermodynamic measurements and the low-temperature-resistance plateau in $\rm SmB_6$ have been investigated and a change in Sm valence at the surface has been obtained from x-ray absorption spectroscopy and x-ray magnetic circular dichroism. Here we show that the statement of the report are not supported by the results from x-ray absorption spectroscopy and x-ray magnetic circular dichroism.
