Abstract
At low temperature, the magnetization and the magnetic susceptibility of the electronic system in quantum-dot superlattices (QDSL’s) of GaAs, InAs, and InSb, respectively, with an isotropic parabolic potential under a magnetic field are investigated on the basis of canonical ensemble statistics including the Zeeman effect. The dependences of the magnetization and the magnetic susceptibility on the confinement frequency of the isotropic parabolic potential and the electronic density in the QDSL’s of GaAs, InSb, and InAs, respectively, are studied numerically at low temperature. Furthermore, the dependences of the peak shifts of the magnetization and the magnetic susceptibility on the effective g-factor value in QDSL’s of GaAs, InSb, and InAs, respectively, at low temperature are obtained numerically.
