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 TN2. 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 || ⟨001⟩,⟨110⟩,⟨111⟩) and to propose additional phase transition inside AF II phase at H1 ≈ 0.5 T.
