摘要：

The magnetic properties of a TbNi2Si2 single crystal have been investigated experimentally by specific heat, anisotropy of the susceptibility and magnetization, and inelastic neutron scattering, leading to the determination of its fundamental coupling parameters. The lowest crystalline electric field states are two singlets close to each other, that explains the different magnetic structures evidenced in TbNiSi2: an amplitude modulated structure, close to T(N), a simple antiferromagnetic one at low temperature and an antiphase one when an external magnetic field is applied along the c direction.
