Magnetisation and susceptibility measurements are reported for the pseudobinary intermetallic
compounds TbxY1-xCu2 (x = 0.1, 0.3, 0.5, 0.7, 0.9 and 1). Metamagnetic behaviour was observed at low
temperatures in this system, except for Tb0.1Y0.9Cu2. The critical magnetic field and the N??el temperature
smoothly decrease with increasing Y content. The temperature dependence of the magnetisation of TbCu2
was studied. The interaction parameters between Tb3+ ions were determined for the compounds
investigated. ?? 1982.
