摘要

Ternary compound Ce3PbC has a simple face-centered cubic CaTiO3-type structure. We found that Ce3PbC undergoes a transition to an antiferromagnetic state at T-N = 8.4 K and shows an another transition at T-I = 5.8 K. Magnetization process exhibits multi-step metamagnetic transitions at T = 1.5 K. The observation of inelastic neutron experiments suggest that the crystalline electric field (CEF) ground state can be consider to be a doublet. This results imply that the Ce sites are influenced by tetragonal CEF interaction, even though the crystal structure is cubic. We expect that such CEF configuration plays an important role in the behavior of multi-step metamagnetic transitions. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 3]
