A spin-glass state (at T \\leq 35 K) for x = 0.016 and 0.025 and a ferromagnetic phase (at T < 60 K) for x \\geq 0.030 are observed. The long range carrier-mediated magnetic interactions are found to be responsible for the observed magnetic ordering for x < 0.045, while for x \\geq 0.045 the spinodal decomposition of Cr ions leads to a maximum and decrease of the Curie temperature, TC, with increasing x.
