【摘要】 通过改变温度和磁场方向对调制掺杂的n型Hg0·82Cd0·16Mn0·02Te/Hg0·3Cd0·7Te第一类量子阱中磁性二维电子气磁阻拍频振荡进行了深入的研究,发现不仅温度的变化能够引起磁阻拍频节点位置的变化.而且改变磁场方向,可以分别调整塞曼分裂和朗道分裂.从对拍频的分析中,可以将依赖于磁场垂直方向的朗道能级分裂和依赖于整个磁场大小的塞曼分裂区分开来.更多还原

【Abstract】 This paper study the detailed magnetoresistance oscillation in Shubnikov_de Hass (SdH) of magnetic two dimensional electron gas consisting of a modulation doped n type Hg_ 0.82 Cd_ 0.16 Mn_ 0.02 Te/Hg_ 0.3 Cd_ 0.7 Te first type quantum well by changing temperature and the angle of the sample with aspect of applied magnetic field, by which found that the changing of temperature and tilt angle will cause the varying of beating node position, By analyzing beating patterns, the magnetic angle dependent Landau splitting can be separated from magnetic magnitude dependent Zeeman splitting.更多还原
