AB  - The ferromagnetic ground states of the half-Heusler compounds AuMnX (X = In, Sn, 
      Sb) have been calculated in the framework of the local spin-density approximation 
      (LSDA) to density functional theory (DFT). AuMnSn is computed to be a 
      half-metallic ferromagnet, whereas AuMnIn and AuMnSb are not half-metallic, due 
      to their different band filling. The computed relativistic electronic structures 
      served as inputs to calculate the magneto-optical Kerr rotations and 
      ellipticities for all three materials. In the case of AuMnSn the largest, 
      zero-temperature, polar Kerr rotation has been found to be -0.45 degrees  at about 1 eV 
      photon energy. The computed MOKE spectra of AuMnSn are in qualitative agreement 
      with recent experiments. The largest Kerr rotations of AuMnIn and AuMnSb have 
      been calculated to be +0.64 degrees  at 4.3 eV and -0.85 degrees  at 0.9 eV, respectively.
