“…(ii) The r xy ðBÞ Hall resistivity exhibits small deviations from linearity, with a knee-like structure more pronounced at the lowest temperatures and practically absent at T , 15 K. This behavior results in oscillations of the Hall coefficient R H around the R cl classical value obtained from the low fields slope of the linear r xy ðBÞ dependence. (iii) The amplitude of the R H oscillation is anomalously large near the EQL with the maximum at a field B M which is slightly larger than B EQL : The above results are qualitatively similar to those found in narrow gap semiconductors such as InSb, InAs and HgCdTe [15,18,19,[22][23][24] although in the most of the latter cases the condition r xy . r xx is generally satisfied at high magnetic fields and only in a few cases r xy just approaches r xx ; as in the present one.…”
