Abstract:
We present a theoretical study of the effect of the spinorbit interaction on
the electron magnetization of small semiconductor quantum dots. Those
characteristics demonstrate quite interesting behavior at zero temperature.
The abrupt changes of the magnetization at low magnetic fields are attributed to the
alternative crossing between the spinsplit electron levels in the energy spectrum,
essentially due to the spinorbit and electron-electron interaction. Detailed
calculation using parameters of InAs and InSb semiconductor quantum dot
demonstrates an enhancement of paramagnetism of the dots.
