Outline of Final Research Achievements

In this study, we performed STM study on Cr atoms doped in II-VI semiconductor ZnTe, in order to clarify the origin of the ferromagnetic character of the diluted magnetic semiconductor, which is expected as one of the promising materials for application to spintronics devices. As results of our STM study, we successfully observed single Cr atoms substituting into Zn sites. And our STS measurements revealed Cr-induced spin-polarized impurity states in the energy gap region of the host ZnTe. Furthermore, we found that the impurity states of neighboring Cr atoms were broadened reflecting the ferromagnetic interaction between them.
