摘要：

Highly Cr-doped II-VI diluted magnetic semiconductor (DMS) Zn1-xCrxTe films with a ferromagnetic long-range order have been grown. A phase diagram of Zn1-xCrxTe in relation to the growth temperature and Cr concentration was determined. Magnetic circular dichroism measurements revealed that a magnetically single phase of DMS Zn1-xCrxTe is obtained in the films with Cr concentration up to x=0.20. Spontaneous magnetization of the film with x=0.20 disappears around 300 K, indicating that the Zn1-xCrxTe is a DMS with room-temperature ferromagnetism. (C) 2003 American Institute of Physics.
