    • Dielectric function of diluted magnetic semiconductors in the infrared regime 
      Aguado, R.; Lopez-Sancho, MP; Sinova, Jairo; Brey, L. (American Physical Society, 2004)
      We present a study of the dielectric function of metallic (III,Mn)V diluted magnetic semiconductors in the infrared regime. Our theoretical approach is based on the kinetic exchange model for carrier induced (III,Mn)V ...
    • Ferromagnetic transition temperature enhancement in (Ga,Mn)As semiconductors by carbon codoping 
      Jungwirth, T.; Masek, J.; Sinova, Jairo; MacDonald, AH. (American Physical Society, 2003)
      We present a theoretical study of (Ga,Mn)(As,C) diluted magnetic semiconductors with high C acceptor density that combines insights from phenomenological model and microscopic approaches. A tight-binding coherent-potential ...
    • Optical properties of metallic (III, Mn)V ferromagnetic semiconductors in the infrared to visible range 
      Hankiewicz, EM; Jungwirth, T.; Dietl, T.; Timm, C.; Sinova, Jairo. (American Physical Society, 2004)
      We report on a study of the ac conductivity and magneto-optical properties of metallic ferromagnetic (III, Mn)V semiconductors in the infrared to visible spectrum at zero temperature. Our analysis is based on the successful ...
    • Prospects for high temperature ferromagnetism in (Ga,Mn)As semiconductors 
      Jungwirth, T.; Wang, KY; Masek, J.; Edmonds, KW; Konig, J.; Sinova, Jairo; Polini, M.; Goncharuk, NA; MacDonald, AH; Sawicki, M.; Rushforth, AW; Campion, RP; Zhao, LX; Foxon, CT; Gallagher, BL. (American Physical Society, 2005)
      We report on a comprehensive combined experimental and theoretical study of Curie temperature trends in (Ga,Mn)As ferromagnetic semiconductors. Broad agreement between theoretical expectations and measured data allows us ...
