采用KKR方法和相干势近似（CPA）研究了（Ga 1 −yIny）1−xMnxAs的电子结构.当x ≥ 0.10时，Ga 1 −xMnxAs的居里温度（TC）高于（Ga 0.5In 0.5）1−xMnxAs和In 1 −xMnxAs。另一方面，Ga 1 −xMnxAs的估计TC在x ≥ 0.05时随着x的增加而饱和，但（Ga 0.5In 0.5）1−xMnxAs和In 1 −xMnxAs的估计TC即使在x>0.10时也不饱和。这些结果与以前的实验结果是一致的。我们的计算结果预测，（Ga 0.5In 0.5）1−xMnxAs和In 1 −xMnxAs的TC将高于Ga 1 −xMnxAs当x ≥ 0.10。
The electronic structures of (Ga1−yIny)1−xMnxAs have been investigated using the Korringa, Kohn and Rostoker (KKR) method with the coherent potential approximation (CPA). The estimated Curie temperature (TC) of Ga1−xMnxAs is higher than that of (Ga0.5In0.5)1−xMnxAs and In1−xMnxAs when x≲0.10. On the other hand, the estimated TC of Ga1−xMnxAs saturates with an increase of x when x≳0.05, but that of (Ga0.5In0.5)1−xMnxAs and In1−xMnxAs does not saturate even when x>0.10. These results are in good agreement with the previous experimental results. Our calculated results predict that the TC of (Ga0.5In0.5)1−xMnxAs and In1−xMnxAs will be higher than that of Ga1−xMnxAs when x≳0.10.
