Abstract

The magnetic, neutron diffraction (ND) and NMR experiments have been performed on (Mn_1-xCu_x)₆₆Ga₃₄ (x = 0.25-0.35). The δ-T curve shows a cusp at T_t after the disappearance of spontaneous magnetization. The x^-1-T curve shows a bend at T_N. The ND experiments exhibit the presence of an antiferromagnetic component lying in the basal plane for T_t ≤ T < TN. For T < T_t, a helical spin structure propagating in the c direction appears, changing the pitch of helix from 4.12C to 8.26C.
