Description

The components-separated magnetic transition in NdCu2Ge2 was investigated by measuring elastic constant and specific heat. The specific heat shows clear peak at TN = 4.8 K The magnetic entropy change reaches Rln2 at ∼ 6 K and Rln8 at ∼ 72 K with increasing temperature. This result indicates that the crystalline electric field ground state of NdCu2Ge2 is a Kramers doublet. In addition, the results of the elastic constant measurements suggest that no degeneracy of quadrupolar degrees of freedom exists below TN. NdCu2Ge2 has a possibility of another mechanism that suppress the magnetic ordering of the ab-component unlike other compounds showing component-separated magnetic transition.
