The anisotropy of charge transport was investigated in the antiferromagnetic II state of GdB6 from precise measurements of transverse magnetoresistance. Based on the data obtained we detected a complicated behavior of magnetoresistance curves which are characterized by the appearance of considerable hysteresis on the field and angular dependences below T-N2. Moreover it was shown that the system GdB6 is sensitive to cooling-warming prehistory. The data analysis allowed to reconstruct magnetic H-T phase diagram of GdB6 along main crystallographic directions (H parallel to < 001 >, < 110 >, < 111 >) and to propose additional phase transition inside AF II phase at H-1 approximate to 0.5 T.
