| 内容記述 | The effect of additional doping of charge impurities was investigated in a ferromagnetic semiconductor Zn1 xCrxTe. It was found that the doping of iodine, which is expected to act as an n-type dopant in ZnTe, brought about a drastic enhancement of the ferromagnetism in Zn1 xCrxTe, while the grown films remained electrically insulating. In particular, at a fixed Cr composition of x 0:05, the ferromagnetic transition temperature TC increased up to 300 K at maximum due to the iodine doping from TC 30 K of the undoped counterpart, while the ferromagnetism disappeared due to the doping of nitrogen as a p-type dopant. The observed systematic correlation of ferromagnetism with the doping of charge impurities of both the p and n type, suggesting a key role of the position of Fermi level within the impurity d state, is discussed on the basis of the double-exchange interaction as a mechanism of ferromagnetism in this material. | |||||||||||||||||
