| Research Abstract |
Aiming at realization of the source of spin injection into semiconductors, we have performed studies for material search of magnetic semiconductors based on II-VI compounds and control and improvement of ferromagnetic properties. Taking the Cr aggregation in (Zn,Cr)Te as a target of our study, we have tried to control the details of Cr aggregation and magnetic properties by changing various conditions of the crystal growth. As a result, we have succeeded in controlling the formation of Cr-aggregated regions by the growth temperature. In addition, we have studied a binary compound CrTe and a quaternary compound (Cd,Mn,Cr)Te and have observed ferromagnetic behaviors in these materials.
