Thermal expansion of GdNi{sub 1{minus}x}Cu{sub x} (x = 0, 0.3 and 0.6) and the non magnetic LaNi and YNi have been measured from 10 K to 300 K using the strain gauge technique. Although changes in the crystalline and magnetic structures occur for x {>=} 0.25 and x {>=} 0.35 respectively, all the compounds show positive spontaneous volume magnetostriction. Combining thermal expansion and specific heat measurements the authors extract the pressure derivative of the ordering temperature. The relation between the magnetic thermal expansion coefficients and the derivative of the magnetic electrical resistivity is analyzed, revealing different behaviors for the ferromagnetic and antiferromagnetic compounds.
