Abstract

The spin polarization (SP) ratio for CdSe quantum dots (QDs) was studied and found to be clearly less than that for Zn1-xMnxSe at low magnetic fields. SP of the CdSe QDs was attributed as arising primarily from the Zeeman splitting of QD states either due to Mn interdiffusion or due to the wave-function overlap of the internal QD states with the surrounding magnetic barrier.
