Abstract From the present experiment, it is clear that in small magnetic field, the energies of spin–up electron state increases with increasing magnetic fields and decreases for spin-down electron states with increasing magnetic fields. At small magnetic field, the energies are determined by the exchange interaction term for both spin up and spin down electron states. At large magnetic field, the exchange term approaches to a constant and the energies are determined mainly by the magnetic confinement term that is the Zeeman term. The analysis made in this research can be useful for predicting tunneling of electrons and holes from core to shell and can have applications in calculating the spin polarized current from the CSQDs
