在4.2 K和更高温度下，在45 kG的磁场下测量了纯铬单晶和单Q态的霍尔系数R H。在每次测量中，在约2和10 kG时发现rh上的异常行为，并且在4.2 K时，在45 kG以下观察到rh符号从正到负的逆转。R H随温度的变化也有2和10 kG的显著变化，并通过磁击穿对Cr自旋密度的间隙进行了讨论。
The Hall coefficient, R H , of single crystal and single Q state of pure Cr was measured in magnetic field up to 45 kG at 4.2 K and in higher temperature. In each measurement, anomalous behaviors on R H were found at about 2 and 10 kG, and reversal of the sign of R H from positive to negative was observed below 45 kG at 4.2 K. Remarkable changes of 2 and 10 kG were also found on R H against temperature and these were discussed through magnetic breakdown with the gaps on spin density weve state of Cr.
