Abstract
The intermetallic compound ErCu has the CsCl structure and is antiferromagnetic1,2 with TN = 16+1K. Resistivity p, specific heat C and magnetization M measurements reported here indicate that a second transition occurs at about 10K. Both the magnetic structure3 and the crystalline electric field CEF parameter4 for ErCu are known. The antiferromagnetic structure is C-type with a propagation vector Q = (1/2, 1/2, 0). The CEF parameters are W = − 0.64K and X = + 0.34 giving a Γ8 (3) quartet ground state. The separation between the Γ (3)8 ground state and the Γ6 first excited state is about 100K.8

Recently Kondo scattering from rare earth ions other than Ce3+ and 463+ has been observed. For example see: A.I. Abou, Aly, S. Bakanowski, N.F. Berk, J.E. Crow and T. Mihalisin, Phys. Rev. Lett. 35. 1387 (1975) for a Kondo system involving Pr3+ and S. Bakanowski, J.E. Crow and T. Mihalisin, Solid State Commun. 22, 241 (1977) for a Kondo system involving Sm3+ ions.
