Exchange couplings in isomorphous [LnCu₂] were evaluated by high-frequency electron paramagnetic resonance and magnetization studies. The exchange parameter J_Ln-Cu was decreased with an increase in the atomic number; J_Ln-Cu/k_B = 4.45(11), 2.27(6), 0.902(10), 0.334(3), and 0.136(8) K for Ln = Gd, Tb, Dy, Ho, and Er, respectively.
