Ferromagnetism of Ga${}_{1-x}$Mn${}_x$As and Weiss theory of Curie temperature in the coherent potential approximation

Sze-Shiang Feng, Mogus Mochena

The zinc-blende GaAs-based III-V diluted magnetic semiconductors (DMS)are studied in the coherent potential approximation(CPA). In this work, we use the exact Hilbert transformatio…
