The magnetic susceptibility of the spin-glass state that may appear in an itinerant-electron antiferromagnet containing magnetic impurities has been calculated as a function of the temperature. The spin-spin interaction mediated by the condensed electrons has been calculated and a short-range interaction of the form (cos 2k//0r/r**2)exp( minus r/ xi //0) has been obtained. A percolation mechanism has been used in order to explain the occurrence of the spin-glass state.
