| Outline of Final Research Achievements |
We have studied the aggregation of magnetic elements in diluted magnetic semiconductors in which a magnetic element is incorporated in a host semiconductor. Using molecular beam epitaxy (MBE) method, we have grown DMSs in which a transition-metal (TM) element Cr or Fe is incorporated in a II-VI semiconductor ZnTe and have investigated the details of aggregation of the TM element and have clarified the correlation with the magnetic properties. In the both DMSs, it was found that the aggregation of the TM elements changes depending on the MBE growth condition, resulting in a noticeable change in the ferromagnetic properties.
