The Hall effect of GdB₆ has been studied on high quality single crystals in the temperature range 2-150 K and in magnetic field of 1 T. The obtained data allow to detect anomalies in the antiferromagnetic (AF) phase including (i) a drastic enhancement of negative Hall coefficient below T_N1 ≈ 15.5 K and (ii) the appearance of an anomalous Hall effect at T_N2 ≈ 4.7 K. Possible scenarios of the AF ground state formation are discussed.
