Abstract

We report here the results of DC magnetization (M) and heat-capacity measurements on the compound TmCu2Si2. Although the results show that this compound is paramagnetic above 3 K, M in the paramagnetic state tends to saturate with the application of magnetic field. This spectacular behaviour of M mimics that known for single-crystal specimens of TmZn and we attribute this ferromagnetic-like tendency to strong 4f quadrupole couplings.
