We have measured at low temperatures the ac differential susceptibility and the electrical resistivity for a series of Gd(Cu1−xGax) pseudo binary alloys for x between 0.10 and 0.22. The Gd(CuGa) system is particularly interesting in this concentration region since high temperature susceptibility measurements have shown a zero paramagnetic &Vthgr; for x?0.15. The intermetallic compound GdCu is antiferromagnetic TN?140 K while GdGa is ferromagnetic Tc?210 K. It was hoped by randomly mixing the Cu and Ga in the x region where Tcand TN→0, a spin glass‐like state could be formed. The susceptibility exhibits a broad maximum around 38 K for all alloys which is relatively concentration independent. At very low temperatures (1–10 K) a shoulder develops in the susceptibility which does vary with x. The resistivity shows an x dependent minimum at high temperatures 80–120 K, followed by a lower temperature maximum at 45–80 K. These behaviours indicate that a simple spin glass freezing is absent and that a complicated form of long range magnetic order is present.
