Magnetic properties of GdMn_{x}Fe_{1-x}Si (x = 1, 0.9, 0.8, 0.7, 0.6, 0) compounds were investigated. Both GdMnSi and GdFeSi crystallize in the CeFeSi-type tetragonal structure and form a complete solid solution without any change in the crystal structure. Magnetic measurements were made in static magnetic fields up to 1 MA/m in the temperature range from 77 K to 420 K. For GdFeSi these measurements were carried out on single crystal sample. It was found that the increase in Fe content leads to a sharp decrease in saturation magnetic moment. The Curie temperature increases in the concentration range 0.7 ≤ x ≤ 1 and monotonously decreases for x ≤ 0.6. These effects could be explained by strong dependence of the exchange integrals on the interatomic distances.
