We investigated magnetic properties of CexLa1−xCu2.05Si2 for 0.01⩽x⩽1, between 2 and 340 K, using the Faraday and the torque method. For x<0.1, magnetic response is found to be given by the single-ion contribution $χ$ion(T), which relates to the Kondo susceptibility of the 4f1 multiplet split by the tetragonal crystal field (CF). For x⩾0.1 the susceptibility is given by Full-size image (<1 K), where $λ$(x) is the x-dependent constant, probably due to Ce–Ce interactions. The anisotropy has a maximum at about 50 K and remains finite for T→0 for all x, reflecting a strong CF influence.
