| 英文摘要 | The magnetisation of heavy holes in iii-v semiconductor quantum wells with rashba spin-orbit coupling (soc) in an external perpendicular magnetic field is studied theoretically. we concentrate on the effects on the magnetisation induced by the system boundary, the rashba soc and the temperature. it is found that the sawtooth-like de haas-van alphen (dhva) oscillations of the magnetisation will change dramatically in the presence of such three factors. especially, the effects of the edge states and rashba soc on the magnetisation are more evident when the magnetic field is smaller. the oscillation center will shift when the boundary effect is considered and the rashba soc will bring beating patterns to the dhva oscillations. these effects on the dhva oscillations are preferably observed at low temperatures. with increasing temperature, the dhva oscillations turn to be blurred and eventually disappear. |
