We have produced Nd1-x Gd (x) Ni4B (0 <= x <= 1.0) compounds by the arc-melting method. Physical properties of the produced samples have been investigated by means of the X-ray powder diffraction, zero field/field cooled magnetization between the temperature interval of 9-70 K, and magnetic hysteresis at 9.5 K. We have observed that the substitution of Gd for Nd leads to a decrease of the unit-cell parameters a, c and the unit-cell volume V. The magnetic phase transition temperatures are found to be 12, 14, 18, 24, 29 and 35 K, for x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0, respectively.
